Local repair of chips and scratches on a car body: how to remove it yourself

How to remove chips on a car body

It's very common for a car to get scratches and chips - this can happen for a number of different reasons.

Stones flying out from under the wheels of your car or any vehicle passing by, bushes and tree branches that can be touched, the car can be scratched in the parking lot by careless motorists, or a hooligan, passing by, will hold a nail, and also in the event of a traffic accident . Any damage to the paintwork must be removed promptly. Otherwise, rust may appear, which will lead to metal corrosion.

Methods for removing chips on a car

There are several ways to remove chips from your car. The coating consists of several layers, which include primer, automotive enamel and varnish coating.

The depth of damage can affect both the top layer and extend to the ground covering. How to remove chips on a car body? Elimination of these damages is carried out in different ways.

The very first thing to do with any method is to wash the car using a special car shampoo to remove all dirt and dust from its surface.

When only the top layer of varnish on the body is damaged, you can remove the fault yourself by polishing the defective area. Only the protective layer becomes thinner to the depth of the damage, and the defect will be impossible to notice. In order to quickly disguise a scratch, you can use a concealer with wax or gel.

When the damage is serious, but does not affect the ground, it can be repaired by painting the part on which the defect was found. If the damage has affected the metal, it can be corrected using degreaser, primer and paint. You can use white spirit, gasoline, or even dishwashing detergent as a degreaser.

But it is better to have such damage removed by a professional car service center so that the work is performed by a master.

Minor scratches and chips

Before treating shallow damage, clean the surface with an abrasive paste.

How to repair chips on a car with your own hands? In order to remove small and not very deep scratches and chips yourself, you will need various types of polishing pastes, sponges, and microfiber cloths.

To carry out the work, you need to thoroughly wash the surface to be treated, then first apply a coarse-grained abrasive paste to a sponge and rub it into the damaged area, the surface becomes a little more matte, the damage on it will disappear, remove the remaining paste with a dry cloth. Using a polish, we achieve shine with our own hands.

Polishing can be done with a special polishing machine or manually using a microfiber cloth. This method should not be used often, as it can damage the varnish layer after a few times. You can also use correctors that contain wax or gel. A wax pencil allows you to repair the chip, and excess wax is removed using a microfiber cloth.

The wax stick will need to be used after each visit to the car wash. A gel corrector looks like a felt-tip pen or tube. It is filled with acrylic paint that fills scratches and hardens to become invisible. If the damage to the body is deep, it is necessary to carefully carry out the operation several times. The gel hardens well and becomes more durable.

There is a possibility that the coating does not adhere tightly to the chip and rust and corrosion form. Using correctors to process the body is not difficult at all.

Repairing chips and moderate scratches

When the primer layer is not damaged, car painting is used to eliminate scratches and chips. Defects can be quickly removed with your own hands using a marker with auto enamel.

It is difficult to guarantee the color so that it is as close as possible to the shade of the original tone, which has changed during use. To select paint, there are palettes that are available in almost all stores that sell car paints.

You need to take any part of the car to the car dealership; it will be used as a sample for selecting the shade of enamel. Very often they take a gas tank cap with them, apply it to the palette and this helps in choosing a paint shade.

You can also choose a color using a computer program, which will select the tone of the paint with almost one hundred percent accuracy. After selecting the color, you can paint the body yourself or leave it to be painted at a salon.

Elimination of deep damage down to the metal

Repairing damage to the body that has already reached the metal will take more time and require more effort. Work to remove chips on a car should be carried out in a dry, well-ventilated area.

It is necessary to clean the chipped area from all dirt and rust using sandpaper, then degrease the cleaned area. The part needs to be leveled, the chipped area needs to be puttied and the surface leveled.

Be sure to apply a layer of anti-corrosion primer to the metal, especially if we carry out work in the fall and winter, and let it dry. If you try to dry the car artificially, the coating may swell. We cover the primer with several layers of paint. At the end we apply a layer of varnish.

But it’s better to go to a car repair shop to carry out such work and entrust the work to professionals. This will cost more than doing the work yourself, but you can get a better result.

Prevention against minor damage to the car body

If you carry out work to protect the car body from external damage in advance, then restoring the coating will be cheaper in the future. There are several protection options:

A polish that forms a protective film over a layer of paint. They are made of Teflon, the protection period is three months. Epoxy polishes protect for up to 12 months. Nanopolishing gives results within 36 months.
Liquid glass (silicate glue). It adheres very well to paintwork and provides protection for approximately 36–38 months; it can be applied by hand and then polished with a soft cloth.
Liquid cover, the cheapest method, looks like a rubber film, which is easy to remove over time.
The protective film is applied to a carefully and thoroughly cleaned surface, which is treated with a special solution. It lasts for several years, you can apply a design on it and it will cost less than airbrushing.
Fabric cover. Installed only on the hood, made to order for a specific car.

By adhering to the recommendations listed, you will reliably protect the body of your car from various types of damage.

Repairing chipped car paintwork - how to do it yourself?

Road traffic accidents, bad roads, active and not always correct operation of vehicles often cause small chips, scratches, dents and similar defects to appear on the paintwork of cars.

The driver may not pay attention to such minor damage, reassuring himself that they are not very noticeable. But this is fraught with serious consequences for the paintwork. Small defects provoke intensive development of corrosion processes caused by the influence of weather and the environment.

After some time, rusty spots form around “insignificant” scratches, which very quickly damage the integrity of the paintwork.

Unnoticeable scratches are replaced by rusty spots that kill the appearance of the vehicle.

They will protect the chassis and save you money, increasing ground clearance by 3 cm.

Scratches, dents and chips in most cases appear on the hood, rear bumper and car body. The method for removing them depends on the size and characteristics of the defects. There are complex and local repairs.

The first method is used in cases of serious damage to the coating. Complex work requires serious preparation of the contractor, knowledge of the various nuances of carrying out repair work.

Therefore, an ordinary driver simply cannot do it on his own.

But local paintwork repairs can be done at home with minimal financial costs. This type of coating restoration is suitable for scratches and small chips, restoration of areas with swollen paint and small dents.

Local repair involves carrying out simple measures aimed at retouching or completely eliminating damage to the paintwork of vehicles without completely painting the problematic body element.

In other words, such work ensures the preservation of the factory paintwork and at the same time guarantees the removal of defects from its surface.

To carry out independent local restoration of paintwork, we will need polishing pastes, sanding paper with P2000 and P1500 grains, finishing or nitro putty, a polishing machine, primer, varnish and paint, auto chemicals for car washing, and solvent. Repairing chips in any car paintwork begins with thoroughly cleaning the vehicle from dirt and dust. We wash the body, hood, bumper using special auto chemicals. Then we clean the car additionally with white spirit.

Next, we find out the type of coverage of our car. The vehicle can be painted:

Acrylic type paint under varnish.
With a regular acrylic (synthetic) composition.
Metallic (pigment of a certain color plus varnish without color).

Almost all foreign cars, starting from the 1990s, have the first type of painting, old Soviet and foreign cars, modern Russian cars - the second, prestigious cars - the third. If you don’t know how your car was painted, we perform a simple paintwork analysis.

Apply a little abrasive paste to any place on the body and polish it with a clean white rag. Then we inspect the rag. If a rich color mark remains on it, we have simple synthetic or acrylic paint.

In cases where the rag remains clean, we can conclude that a layer of varnish was applied over the coloring composition. Based on this, we purchase the required materials for repairs.

The idea of removing small scratches is to prepare the surface and renew the paintwork locally or on the entire car

We inspect the surface of the car and determine the severity of the existing defects.

To repair medium and fairly deep damage, around which rust has already begun to appear, we clean the problem area from corrosion using a sharp knife (we work with its tip) or a sharpened needle file.

After this, we treat the damaged part of the surface of the part with P1500 sandpaper and apply a small amount of acrylic primer to it. We wait a quarter of an hour. We re-treat the area to be repaired with a primer, and then leave the car alone for 2.5–3 hours.

https://www.youtube.com/watch?v=TviJK-6XnRk

After the primer composition has dried, you can begin painting the area of the part that requires restoration. Painting is done with a suitable color composition. We select the desired paint according to the VIN code of the car. Next we proceed according to this scheme.

Mix the paint thoroughly and apply it to the damaged area in thin layers. After applying each layer, wait at least 15–20 minutes for it to dry. And only after the specified time has passed, we apply the next layer of paint.

Depending on the depth and complexity of the chip, we will have to apply up to 6–10 layers. The point here is that the paint shrinks noticeably as it dries. As a result of layer-by-layer painting, we should get a tubercle (bump) with a small influx of paint at the chip site.

We restore the coating with varnish using the same algorithm. But in this case, we apply the last layers with a colorless varnish composition. We take a break for a couple of days. And then we start sanding the paint bumps.

We must ensure that they are completely level with the main surface of the body or other repaired part:

We treat the area around the tubercle with a putty compound (it is most convenient and safe to apply it with a silicone or soft rubber spatula). We are waiting for the putty to dry.
Take a small flat block of wood. We wrap it with R1500 sandpaper. We sand the surface by hand, regularly washing the area to be treated and the sanding paper itself with water. There is no need to press the bar.
When the bump disappears (it should not be visible visually), take the P2000 sandpaper and use it to finish the repaired chip.

With a high-quality and responsible approach, sanding old paint is indispensable

The defect has been resolved. But the restored element of the car (body, hood), after all the described operations, visually has an uneven color. We need to get rid of stains where deep scratches and chips were removed.

This can be achieved using the same P2000 sandpaper. We treat the restored surface with it. The operation is performed using a wet technique. Simply add water to the hood and use circular movements to even out the color of the coating. We act carefully.

We do not allow strong pressure on the sandpaper, so as not to rub the paintwork down to the ground.

After painting and sanding the car's surface, we begin polishing it. The procedure is carried out using sets of special abrasive pastes under the 3M brand or other brands. The operation is performed using a special polishing machine equipped with foam rubber circles.

We need to alternately treat the coating that has undergone local repairs with three pastes - coarse, fine and non-abrasive. This part of paintwork restoration does not cause any significant difficulties for home craftsmen. The polishing machine will do everything itself.

We only need to change the foam circles for each specific paste.

Shallow scratches and dents can be easily removed from the paintwork. In most cases, it is enough to disguise them with a composition from a special restorative pencil (sold at any auto store). If this method does not lead to the desired result (elimination of the scratch), you can perform local painting of the defective area.

Now let’s see how you can restore the car’s coating in areas where the paint has blistered. Similar damage appears after improper painting of the car due to the fact that air bubbles penetrate under the paintwork. The procedure will be as follows:

We remove the paint layer near the swollen area.
We clean the places where there is rust. We treat them with a primer with anti-corrosion properties.
Apply paint layer by layer to the cleaned and primed area. Important! We stop painting after the thickness of the factory coating is equal to the thickness of the fresh paint.
We sand and polish the paintwork.

There is nothing complicated about local vehicle coating repairs. You can actually do all the work yourself, without resorting to the services of technicians. centers. Let us add that experts do not recommend driving your car out of the garage for 12–18 hours after paintwork repairs. This time will be enough for the paint to dry completely.

We repair chips and scratches on the car body with our own hands

Every car enthusiast cares about the appearance of his car. But sometimes, during use, scratches and chips that are not at all pleasing to the eye appear on it.

This moment is quite unpleasant for the car owner, not only because the car loses its aesthetic appearance, but also because it is in the places of scratches and chips that corrosion and rust begin to develop.

Therefore, it is very important to get rid of such minor damage as quickly as possible, since delaying repairs will lead to even greater financial costs. You will learn how to independently repair car body scratches and small chips from this article.

Not every car enthusiast will like this type of car.

All scratches that may appear on a car body can be divided into several types. These are scratches on the top layer of paint, scratches to the ground level, and scratches to the metal. Each of these types of elimination requires its own approach, which will be discussed below.

Video - local scratch removal

Getting rid of scratches

Let's start with the smallest and least costly damage - scratches on the top layer of paint. Removing such a scratch is quite easy. There are several ways to do this kind of work.

One of them is polishing the body surface. This kind of work can only be done if the scratch has not reached the ground level. For polishing you will need special pastes that will help remove a thin layer of paint at the scratch and level it to the same level.

In this matter, it is necessary to remember that the car is not painted, but on the contrary, a layer of paint is removed. Care and attention will be required here, because you can overdo it and polish it down to a layer of primer. Then you will have to paint not only the scratch, but the entire polished area.

And this will lead to additional costs of money and time.

The second way to eliminate scratches that have not reached the primer layer is to treat it with a wax pencil.

The best effect of this method can be achieved if, after using a wax pencil, the surface is treated with a color-enriched polish.

It should be remembered that before using a wax pencil, the car must be thoroughly washed and the scratch area must be cleaned with gasoline or white spirit.

Removing a scratch using a wax pencil is quite easy.

If the scratch has not affected the soil layer, but is very wide in itself, you will not get away with polishing and a wax pencil. In any case, it will have to be painted. It will be enough to paint only the scratch. To do this job, you can cover the scratch on both sides with adhesive tape or masking tape.

To apply paint, you can use a brush that girls use to paint their nails. The main thing is to thoroughly rinse it in acetone beforehand and thin it out a little. If you don't have a nail polish bottle on hand, you can use a matchstick, slightly ruffled at the end, as a brush.

And do not forget that before applying paint, you need to carry out the same operations as before any painting - thoroughly wash the car and treat the area to be painted with white spirit or gasoline.

If the scratch has touched a layer of soil, there are also two possible solutions to this problem. The first one is only suitable for very thin and small scratches. It consists, as in the previous case, of covering up scratches with a wax pencil. Again, don’t forget about pre-treating the scratch and washing the car. But don't be fooled. This method has one big drawback.

Over time, the layer of wax will begin to disappear, and the scratch will become more and more noticeable. Therefore, such processing will have to be performed again and again at certain intervals and, to avoid this, it is best to tint the scratch area. In this case, two layers of paint are applied after preliminary preparation.

If you notice a wide scratch that has reached the ground, forget about the wax pencil, it will not help in this matter. The only way to help here is to paint the damaged area. To do this, the scratch area must be washed and treated, as mentioned above, with gasoline or white spirit. Then it won’t hurt to cover the problem area with adhesive tape around the perimeter and apply two layers of paint.

This method is much more reliable and effective than a wax pencil, and it is done only once, unlike the first.

What should you do if the scratch went through the top layer of paint, the primer layer and reached the metal? Although this damage is one of the most unpleasant, there are also ways to repair it. You won't get away with ordinary painting, much less a wax pencil.

First of all, as in all cases, the car should be thoroughly washed with foam and dried. Then the standard process is treatment with white spirit or gasoline. After this, wipe the car again in the area of damage, first with a damp, then with a dry cloth.

If corrosion elements are already visible at the scratch site, the next step is to apply an anti-corrosion primer. This element should never be omitted, since painting a deep scratch without anti-corrosion primer can lead to unexpected results.

Corrosion and rust will continue to develop under the paint layer, and will soon ruin all your efforts. Having completed this stage, we move on to the next one - applying a thin layer of regular primer. This is done so that the paint adheres better, and a deep scratch without primer will be slightly noticeable.

Next we move on to painting. Here, on top of a thin layer of primer, you need to apply two, or preferably three, layers of paint, and then let it dry well.

Sometimes car owners have problems with parking, in which bumpers often suffer.

Therefore, scratches on bumpers are a fairly common problem that cannot be ignored.

The plastic bumper is not subject to corrosion and rust, so everything is simple here - cleaning from dirt, treating with gasoline and touching up with acrylic varnish from a repair can or paint.

If your car has metallic paint, everything is the same with one small feature. It consists in the fact that after painting, the painted layer has a little more shine, which sometimes becomes very noticeable. To eliminate this problem, the painted area is covered with a thin layer of varnish. This virtually eliminates the difference in the reflective properties of the two areas.

Thus, you now know how to eliminate scratches on the car body, both deep and wide, and small superficial ones. At the same time, do not forget that the scratch must be treated and removed as soon as possible, because corrosion and rust may soon form in its place.

Working on paint chips

The scratches have been dealt with, but there is another common problem with the car body – paint chips. Paint chips, even with a shallow depth, have a fairly large area, so a wax pencil is not used here.

If the depth of the chip is small, treating the problem area with a color-enriching polish, followed by a layer of protective polish, can help. Before processing, the surface should be cleaned and degreased. In the case where the chip has reached the layer of soil or metal, the polish is useless, and touch-up of the chipped area cannot be avoided.

Some car owners are faced with the problem of blistering paint. The damage is quite unpleasant, since pockets of rust and corrosion appear under these swellings. Therefore, this problem must be dealt with immediately. To do this, you need to carefully open the bottle and remove all remaining paint.

You should remove enough so that the remaining paint adheres securely to the car body. If, after opening the bottle, you find traces of corrosion or rust underneath, you must remove it and treat the area with anti-corrosion primer. Then you can start painting.

The paint is applied in several layers so that it is equal in level to the old layer.

Body dents

Next, we’ll look at how to eliminate a small body defect, namely dents. If small dents appear on your car, you can also do the work to eliminate them yourself. This process is called straightening. For it you will need a wooden or nylon mallet, rubber or metal backing.

You can fix a small dent on your car yourself

If the dent is small and there is no damage to the paintwork, simply squeezing the dent out from the back side with your hand often helps. As you may have guessed, this will require access to the part being repaired from both sides, so the element often has to be removed and disassembled.

Removing scratches on a car body without painting

To remove scratches from a car body, not in all cases the damaged areas of the paintwork need to be repainted. Often, shallow scratches can be removed without painting the car body. After all, anything can happen on the roads, and often even professional drivers are faced with the problem of various kinds of scratches appearing on the body.

The reason for their appearance is not always the level of driving skills. Scratches on the car body can be the result of careless driving by other road users. Also, the causes of scratches can be branches and tall dry grass on country roads, or aggressive dust and stones from the roadsides.

In any case, regardless of the reasons for their appearance, scratches on the car body must be removed. However, in such situations it is not always worth turning to expensive specialists for help, since in many cases you can cope with the problem yourself.

How to remove scratches on a car body

Before removing scratches from the car body, you should first wash the car thoroughly (instructions on how to properly wash a car).

Then, on a cleaned body, it will be possible to assess the degree of damage to the paintwork (abbreviated as paintwork) and the depth of the scratches, and then determine how to remove them.

Based on the depth and size of scratches on the car body, the following options for removing them are possible:

Removing scratches and small chips by polishing the body (manually or using a polishing machine);
Shallow scratches of the varnish coating and other minor damage are removed using a restoration pencil (for example, Fix it Pro), colored wax or nanocompositions such as RENUMAX;
Serious damage to paintwork, such as deep scratches down to “living” metal, is almost impossible to remove without painting. In such cases, you will have to spend a lot of money on touch-up paint.

Let's look at each of the methods for removing scratches from a car body in more detail and weigh their pros and cons.

Removing scratches on a car body by polishing

Polishing is one of the most effective ways to remove scratches on a car body without painting. Depending on the depth and area of damage to the paintwork, scratches can be polished manually or using a polishing machine.

The body is manually polished with a soft cloth using polish, which can be purchased at any auto shop. You just need to follow the instructions, which are usually found on the back of the polish bottle, to relatively quickly remove minor scratches from the car body.
It is a completely different matter to remove scratches by polishing the body using a polishing machine. In this case, you cannot do without special knowledge and equipment.

Car body polishing can be either protective or abrasive:

With protective polishing you give your car shine and shine, while eliminating minor scratches on the car body;
By abrasive polishing using polishing pastes, you can remove not only scratches, but also chips, abrasions and other not very serious damage to the paintwork that can be removed without painting the car.

Since the second method of polishing is quite labor-intensive and requires some skill, we recommend that you read our instructions for polishing a car body with your own hands.

Removing scratches on the body with a Fix it Pro pencil

If there is only superficial damage to the varnish coating, then there is an excellent way to remove such scratches that does not require specific skills and can be done by any amateur - this is a special pencil for removing scratches Fix it Pro.

After just a few uses, the Fix it Pro pencil will not leave any traces of scratches on the surface of the body. The main advantages of the Fix it Pro pencil are:

Simplicity and ease of use;
It matches any car color;
Almost instantly removes small scratches and chips;
Fix it Pro can be used multiple times;
A very affordable price and an opportunity to save on a visit to a car service center.

However, in fairness, it is worth noting that small scratches can be easily removed not only with a pencil. According to “experienced” motorists, RENUMAX compositions cope more effectively with scratches and other minor damage to a car’s paintwork.

And given the low cost and ease of use, RENUMAX can confidently be called one of the most popular means for removing scratches on a car body without painting.

But still, miracles do not happen and you should remember that both the Fix it Pro pencil and the RENUMAX product will help restore ONLY the varnish coating of the car, and not the paint.

Tips for removing scratches with partial body touch-up

If there is deep and extensive damage to the paintwork, it would be more advisable to remove scratches on the car body using paint and varnish. They are available at retail in small bottles and are designed specifically for local correction.

But in addition to some labor-intensiveness of this process, you will also need to work hard on selecting the desired color and shade of paint (see the video below).

If, due to the degree of damage to the paintwork, you need to use putty, do not neglect this procedure. It is advisable to entrust all complex work to qualified specialists who will competently carry out restoration work and help achieve an impeccable result.

However, if you have “straight” hands and some experience, you can independently remove almost any scratches from the car body (both without painting and with touch-up of the damaged areas). It is worth taking into account that all work must be carried out in a clean, dry and warm room with sufficient lighting. Before starting touch-up painting, it is advisable to warm up the car body.

How to remove scratches on a car body without painting yourself

No matter how carefully the driver drives the car, scratches will appear on the body over time.

This cannot be avoided, since damage to the paintwork is most often caused by factors that do not depend on the driver’s driving skill.

Branches of trees and bushes, tall grass, stones and sand flying off when driving at high speed, as well as many other reasons will lead to damage to the car body.

To remove scratches from a car's paintwork, you must first wash the body and determine the extent of the damage. Depending on the depth of the scratch, you need to choose a method for restoring the surface. Medium-depth chips and scratches that do not reach the metal can be removed without painting.

How to remove shallow scratches from a car body

Shallow scratches occur on every car over time. Most often they affect the lower halves of the doors and other parts of the body located below the hood.

Their appearance is due to the fact that when driving along a highway or other road at high speed, sand, small pebbles, glass and other debris fly out from under the wheels of the surrounding cars, which bounces into the paintwork of the car.

It is impossible to avoid such damage, but they can be removed quite simply without contacting a service center.

Polishing will help get rid of shallow scratches on your car. Depending on the area of damage to the body and the depth of the resulting scratches, you need to choose the option of manual or automatic polishing.

To remove scratches by hand, you need to have a soft, lint-free cloth. A polish is applied to it, which can be bought at any specialized automotive store. Next, you need to follow the instructions indicated on the bottle of surface polishing agent. The process is quite simple, but time consuming.

If the body is strewn with shallow scratches, it is better to choose the automatic polishing option. To work, you will need to acquire a polishing machine and read the detailed instructions for polishing a car body yourself. In this case we are talking about abrasive polishing, which allows you to eliminate damage to the paintwork.

Local removal of scratches and chips from the car body

It makes sense to polish a car if the car is covered with shallow scratches that spoil the appearance of the body.

However, sometimes it is necessary to eliminate one shallow scratch or small chip that was caused, for example, by a tree branch while parking.

In this case, it is not practical to polish the entire car, and it makes sense to use one of the following methods:

Use a wax pencil. Wax pencils can be found in automotive stores to remove scratches. They are produced by different companies, but their operating principle is the same. Using wax, a chip or scratch is painted over, and excess wax is removed using a microfiber cloth. Before starting work, be sure to degrease the area where the product will be applied. Please note: The Fix it Pro pencil is widely advertised, which, according to manufacturers, can save the car body from even the deepest scratches. In fact, such a pencil is no different in effectiveness from other wax tools for removing scratches, but its cost is several times higher.
Use gel corrector. You can buy gel correctors in various colors in automotive stores. You need to choose the most suitable option for the body shade. The principle of operation of such correctors is very simple - they are filled with acrylic paint, which fills scratches and dries. Correctors can be made in the form of a felt-tip pen or tube.
Use a set of corrective tools. It is recommended to remove medium-depth scratches using special kits that can be found on sale. They include a bottle of polymer, degreaser, car polish and wipes. The varnish must be applied extremely carefully, without protruding beyond the boundaries of the scratch. Important: The corrective kit should only be used if the paint used for the body does not contain metallic pigment.

Removing deep scratches from a car body

If the car's paintwork has been seriously damaged, only painting will allow the body to return to its original appearance. If measures are not taken in time, rust will begin to appear at the site of the “injury” over time, which is dangerous for the body.

Car body painting is a complex process that requires attention to detail. For the work you will need sandpaper, polish, primer and paint of the same color. The car painting process consists of the following steps:

Cleaning the damaged surface from dirt, paint residues and rust. To do this, use sandpaper with a grit of P1500 or P2000. It is necessary to rub a surface slightly larger than the actual damage in order to eliminate corrosion completely if it has already begun to spread;
If there is a dent at the damage site, you will need to use automotive putty to level the surface. When the putty is applied and dried, it must be sanded with sandpaper to ensure a perfectly smooth surface;
Regardless of whether putty was applied or not, the next stage of work is priming the damaged surface. To apply it, it is advisable to use a spray can or brush. When the primer dries, it will also need to be sanded using sandpaper and water;
Next, the surface is degreased with a special product or white spirit;
The final stage is the actual application of paint and varnish.

When painting, it is important to pay attention to the tone of the paint being applied. The real shade of the car does not always coincide with the one recorded in the car's passport. When “aging” under the influence of climatic conditions, the body changes its color slightly, and computer diagnostics allows you to select the current shade of the car body as accurately as possible.

Removing scratches from a car's surface

Often, the body of a car receives some degree of damage as a result of being involved in a traffic accident. But the body can be damaged during normal use.

About 50 percent of cars have minor damage, in this
case we are talking about scratches on the body, abrasions, chips from stones on the hood, deformations and cracks, due to the presence of which the appearance of the car significantly deteriorates and requires body repairs and removal of scratches on the car and its painting.

Classification of paintwork damage

Scratches on a car body can be roughly classified as follows:

Scratches that have not affected the base coat of paint - repairing scratches in such cases usually comes down to polishing.
Scratches, chips, abrasions are small in size, but the paintwork has been damaged (soil or metal is visible) - to remove such damage, the method of local body repair and local painting of existing scratches is used;
Deep scratches, chips that affect not only the paint layer, but also the metal of the body - repairing such damage is more difficult. Before you begin removing deep scratches on your car, you will need to restore the geometry.

In the event that the area of scratches or chips is small and depending on where they are located, for example, on the hood or wings, there is a possibility that everything can be done with local painting of the damaged area.

If a scratch or abrasion occupies fifty or more percent of the area of a body part (along the entire door or fender) or if the chip is quite large and is located on the hood (in its central part), then in this case the entire part will need to be repainted.

Old scratches and chips with a coating of rust and corrosion.
To remove these scratches and eliminate chips, the damaged area will need to be cleaned to bare metal, possibly using a rust converter.

Car body repair is conventionally divided into two groups – local and comprehensive repairs. Comprehensive repairs are carried out to restore geometry, overhaul the body and other body work. Local car body repairs include work related to:

Removing scratches on a car, repairing and painting scratches and abrasions;
Dent repair without painting,
hail damage repair;
Removing chips, repairing and painting chips.

In what cases can scratches and chips be removed without painting?

In case of surface scratches, only the top layer of varnish is damaged, but the base (factory) layer of paint remains intact and the body part is not deformed.

In this case, in order to remove minor scratches on a car, it will be enough to simply polish the damage, and then apply protective layers to the treated area in accordance with technology.

Small scratches are easy to notice after an automatic car wash. The most visible scratches are located on the hood, fenders and doors of the car.

It must be remembered
that if you regularly apply a layer of polish, which allows you to protect the paintwork of the car from minor scratches on the body, from sand flying out from under the wheels, and from the hard bristles of a brush used to remove snow in winter, the cost of removing scratches will be much less likely.

Removing dents without painting

If a car body part was deformed, but the dent did not lead to cracking of the paintwork, then in this case a vacuum method can be used to remove the dents without repainting.

Using a set of special tools used for removing dents, specialists will quickly remove marks left on the hood and roof from hail, and traces of “contact parking” on the fenders and doors of the car.

Removing deep scratches on a car and chips on the body, in case of damage to the factory paintwork and damage to the surface layer of the metal.

Repair of such scratches and chips, regardless of their location on the car, must be done as soon as possible. After all, if the paintwork has been damaged down to the metal, then this is actually an open door for moisture and the active components of various reagents used to treat roads in winter, due to which the process of metal corrosion is accelerated.

Such scratches are dangerous because, over time, rust will form in the damaged areas, and the paintwork of the body itself will gradually deteriorate, crack and peel off.

Chips on paintwork are formed while the machine is moving, due to exposure to air currents mixed with fine abrasives (sand and stones).

Depending on the speed of the vehicle and the size of the stone that got into it, the chips will vary in depth and intensity of formation.

The largest number of chips, as a rule, are located on the hood, as well as the front fenders of the car. A spot chip in the paintwork of a car body is dangerous primarily because metal corrosion occurs quite quickly at the site of damage.

Therefore, repairing and painting scratches, as well as repairing chips, should be carried out as quickly as possible, this is especially advisable in the case when it is necessary to remove deep scratches on the car to the metal, due to the fact that the latter will begin to oxidize, and then Rust and corrosion of the metal will follow.

Local repair of scratches and chips

In order to remove scratches, repair chips and abrasions with dents, where there is damage to the paint layer and metal surface, painting is necessary.

But using the local repair method makes it possible to remove scratches on the hood, fenders, as well as on the doors or trunk lid, by painting only a small, damaged area of this part, without resorting to complete repainting.

Local repair of scratches and chips

The use of local painting of scratches makes it possible
to preserve the original paintwork as much as possible, while the cost of work and the time spent on repairing scratches will be minimal. When using local repair technologies, it is not necessary to completely paint the car body and its parts.

Local repair technology

Local repair of scratches and chips

The first specialist who will receive a damaged car is the manager, who will determine the extent of the damage, as well as a list of repair and restoration work that will need to be carried out.

Next, the colorist gets down to business - he is a specialist who is able to establish the enamel shade code with pinpoint accuracy using a set of special standards.

It is worth noting that local repair technology is based on the use of putties and enamels made on the same polymer base, which makes it possible to create a very durable, uniform layer of newly applied paintwork that will prevent swelling, peeling and peeling.

After this, the damaged and exfoliated layers of enamel and putty are removed. If a chip or scratch on the car body is old and there is already a layer of rust underneath, the repair site is cleaned to bare metal, sometimes using a rust converter.

The process of applying putty, despite its apparent simplicity, is essentially a basic operation.

Quite often, in order to remove scratches from a car body, it is necessary to apply several layers of putty, and the quality of the paintwork and the repair as a whole will directly depend on how carefully the putty is applied and layer-by-layer drying is carried out.

After this, the putty is sanded. The completion of the entire process is the application of enamel. This body repair technology involves applying a multi-layer (up to 5-7 layers) coating. This work must be carried out with drying of the intermediate layers of coating.

Local repairs are carried out in a small area, with the minimum possible overlap of the factory paintwork.

This is one of the most important differences between local repair technology and the traditional repair method of painting the entire part.

The capabilities of this technology are so great that, if necessary, it is possible to give the paintwork of the body almost any texture.

Finish the painting by drying the varnish, as well as polishing the area that was painted. As a rule, work to restore enamel for damage such as: scratches on the car body, abrasions from contact with obstacles - garage doors, fencing or another car (in the absence of strong dents) takes about 3-4 hours.

Advantages of local repair:

Local repair technology is primarily aimed at maximizing the preservation of the original paintwork.
The part will not be repainted, and accordingly, the selling price of the car as a whole will not change.
It is quite important that all work is carried out without dismantling body parts - this allows the tightness of welds and bolted joints to be maintained.
Repair time is significantly reduced. An important role is played by the factor of saving money.
As a result of the above repair work, at the site of damage to the body, a strong, multilayer, monolithic, polymer structure is formed, “grown” into the layer of the original factory coating. Accordingly, joint stresses do not occur (as in the case of inept “manual” repairs using a can of paint), the coating will remain uniform, and will not contribute to repeated corrosion.

In conclusion, it should be noted that high-quality repair of scratches and their painting, removal of chips on the car body can only be done by true professionals in this matter.

It is also worth saying that the opinion of those car owners who believe that the paintwork of a car body can always remain perfect is erroneous. When using a car, minor damage is inevitable. Therefore, it is important to remember that you can always quickly and efficiently remove damage to the body.

And therefore, if scratches or small dents appear on the car body, you should not be upset!
