Paint chips on a car body are almost impossible to avoid, so you need to know how to get rid of them. Fortunately, it's not difficult at all.

Like deep scratches, chips can contribute to rust. To avoid this, you do not need to repaint the entire part - it is quite enough to repair the chip locally. To do this, you will need body-color paint, a touch-up tool or toothpicks, body wax, degreaser, and a microfiber towel.

To begin, carefully and treat the area of ​​the chip with a degreaser to remove dust, dirt, traces of wax and ensure good grip surface paints. Then take the paint matched to the color code and shake the bottle well. You will need a special ball tool for touching up, and if you don’t have one, ordinary toothpicks.

Carefully fill the chipped cavity with thin coats of paint, allowing each one to dry for a few minutes before adding the next. Be aware that paint shrinks as it dries. Apply a layer on top if necessary. clear varnish. After that, wax the surface to protect it from water and dirt.

Minor scratches and chips are the most common car paint damage. Branches from bushes and trees, small pebbles or other unforeseen situations can leave their imprint on the body iron horse, making his owner pretty nervous. Is it worth giving in to despair and how to remove scratches on the car yourself? One option is to contact a car service and make up for imperfections for a certain cost. But why waste money and time if you remove small chips you can at home.uuii

Contacting a car service is one of the options for removing a scratch

Before proceeding with the restoration, it is necessary to have an understanding of the surface layers car body. Lacquer comes first, then base enamel, primer, phosphate layer and steel sheet.

Paint damage vehicle can be divided into three groups: abrasions of the top layer of paint, to the level of the ground and deep scratches to the metal. It is important to note that body scratches at the metal level require mandatory anti-corrosion treatment especially during the autumn-winter period. In this case, if the damage area is less than 30% of the body part, only the defect area is processed.

Without painting, deep scratches and chips cannot be removed with your own hands.

To carry out painting work, you will need P1500 or P2000 sandpaper, a primer, an identical paintwork and polish. Before buying paint, experts advise to produce computer diagnostics, which will reproduce the desired tone of car paint, taking into account wear.

Due to change climatic conditions, body painting may change color and the restored area will differ significantly in color scheme from the rest of the surface.

It is also worth paying attention to the fact that if the car has a solid color without a metallic effect, it is necessary to mix the paint with the activator in the proportions indicated on the can. On the contrary, the presence of a pearlescent or metallic shade indicates a two-layer paintwork, the restoration of which involves the application of a quick-drying base, and after varnish.

At the first stage of work, it is necessary to clean the damaged area from dirt and rust with sandpaper. In this case, rationality should be observed, since the more area is overwritten, the more will have to be painted over.

Corrosion must be removed carefully. If there is a dent in its place, it must be leveled. Its layer should be no more than 3 mm. To sand the putty, we use coarse-grained sandpaper, and then fine-grained sandpaper. This will help achieve a perfectly flat surface.

The next step in auto painting involves applying a primer. It is best applied with a sprayer or brush. After the primer mixture has dried, we proceed to polishing it using water. Finally, the surface is degreased and painted. The best option will be the use of an airbrush to spray paint.

Painting takes place in three stages. The first and second are made with a difference of about half an hour, which will allow the coating to dry. Lacquer is applied as a third layer.

Restoration of the paintwork of the body must be carried out indoors. If this is not possible, then it is important to carefully ensure that precipitation or dust does not fall on the surface to be treated.

The damaged area of ​​the car must be prepared by washing, drying and degreasing. As a degreaser, White Spirit or gasoline is perfect. You should monitor the amount of the agent used, since its search may not be the best way to affect the body painting. Alternatively, instead of White Spirit, you can use " folk remedy" - dishwashing liquid.

It is important to follow the prescribed instructions before using a polish, wax or gel stick to avoid damaging the car's paint.

After painting work, it is necessary to wait for the natural drying of the paint within 24 hours. Artificial drying may blister the surface.

Over time, during operation, in almost any conditions, on the car appear minor defects body or bumpers in the form of scratches and chips. These paint damages are not only disadvantages from an aesthetic point of view, but also represent a practical danger to the car body. Therefore, it is desirable to eliminate the chips that have appeared as soon as possible. This will protect the car body from the harmful effects of corrosion. Sometimes, even small chip, which is almost invisible to others, but knowing about it, it constantly “cuts” your eye, causing constant discomfort. Is it possible to fix car scratches yourself? Yes, it is possible, and it does not require high qualifications or large financial costs.

Of course, there is the easiest option - to contact the experts. However, such a seemingly simple operation can be quite expensive, or the quality will be, as they say, even worse than it was, that is, even more noticeable. This also often happens and then you have to pay again and more to correct what you have done. The choice is yours - if you have money and no desire to mess around, it's better not to save money, but immediately contact a decent company. Further article for those who want and can do minor repairs your car on your own.

At in large numbers damage, it makes no sense to make spot body repairs. Indeed, in this case, your hood or bumper will be covered with spots or dots with a slightly different color, and the process of spot repair itself will be quite long and laborious. In this case, it is better to paint the entire body part. The painting process is quite complicated, but you can do it yourself. However, whether it will be better and cheaper is up to you. Since this will already require special tools, materials and skills.

If the chips are small and there are not very many of them and there is no metal corrosion, this is just what you can quite easily fix on your own.

To protect the car body from impacts environment manufacturers use multi-layer protection, which is a combination of several various materials. The strengthened structure of such a coating is shown in the figure. IN modern cars iron is pre-exposed additional protection- galvanized. Thickness and quality may vary.

Therefore, when starting repairs, at least two types can be distinguished minor damage car paintwork:

  • affecting iron;
  • not reached iron.

The fact is that in each of these cases, the restoration of the paintwork should be done correctly in different ways. If the damage affected only the varnish and paint, for example shallow scratch, to eliminate it, it is enough to treat the area with a polish. In the event that the violation of the paintwork turned out to be deeper, damaged iron, the repair will be a little more difficult.

There are several different approaches to how to properly paint cracks on car, and each of them has its supporters and opponents. But in any case, paint is applied to the place of damage, which forms a kind of dome above it, and it must be treated with a polish to bring it to general level existing paintwork. This will make the repaired area less visible. Visibility is most affected by the accuracy of paint selection.

Consider the most common ways to eliminate chips and scratches:

1. Polish, anti-scratch, polishing pastes.

Able to remove scratches chips on the car, which affect only the varnish surface of the car and do not reach the paint. These products often have abrasive substances in their composition, due to which the top layer of varnish is rubbed off and the surface, leveling, again becomes supposedly smooth and shiny.

Polishes are selected depending on the size of the scratch. But you should not get carried away with these tools, because you can remove the layer of varnish completely.

2. Wax pencil, color enriched polish

They allow you to remove scratches from a car that affect not only the varnish, but also the paint layer. These products fill the damaged surface, thereby protecting it from corrosion.

In addition to the advantages, these funds have significant disadvantage: after prolonged exposure to water, they are washed off, and if you do not have a standard car color (black, white or red), but, for example, light green with a metallic effect, then the scratch will still be visible.

3. Restoration pencil

Eliminates the most serious scratches and chips on the car, which have reached the metal or ground. The restoration pencil is a tube with car paint and a brush.

Colors are usually matched to the vehicle's color code. The scratch remover is the most reliable tool we've reviewed as the paint doesn't wash off and protects the car from corrosion. The only caveat is that in some specific cases it is difficult to choose a tool, since not all coded car paints are in pencils. In such cases, the colors are selected visually according to the catalog with real colors.

4. Paint

If the chip is very small, take a match or a toothpick and apply a drop of paint to the washed and dry chipped area. When the paint hardens a little, you can smooth it out with a small brush. The paint is selected according to the number of the car from the colorists or according to the details of the car (for example, the gas tank hatches). Over time, the paint fades a little, so the method of selecting a car detail is more preferable.
You also need a little varnish and hardener to it. In the right proportions, mix the paint with varnish and hardener. Tint with a small margin. After drying, at least a day, it is polished with a professional 3M polish, You can trim it with a two-thousandth sandpaper before polishing.

5. If the chip got to the metal and caused corrosion

IN this case the repair of the chip will be more difficult and long, since it is necessary to remove the begun processes of corrosion and the spread of rust. To do this, you need to use the traditional body repair, which will remove rust and allow you to locally paint over the part without visible differences from the rest of the body.

To eliminate such a chip, you will need sandpaper with a grit of 600, 800 and 1000, possibly putty, primer and paint, as well as tools for their application, degreasing solvent. The workflow in this case is as follows:

  • First, it is necessary to clean the local cleavage on the car, taking into account the possible spread of corrosion under the paint.
  • Rust must be brushed down to the metal, then the surface should be washed and degreased. Places where corrosion has been removed should preferably be treated with a primer. You can use an acrylic two-component primer from a spray can. It will be required for these works a few drops. A thin brush or a sharpened match is applied to the metal. After 10-15 minutes it is necessary to apply a second layer. After that, they wait about 2 hours until the soil is completely dry, or accelerate it by heating.
  • If necessary, apply putty, let it dry and use 600 and 800 grit sandpaper to meet the requirements.
  • Degrease the surface again and, if necessary, apply a primer, which should then be washed out with 1000 sandpaper and water.
  • After that, the final degreasing and painting takes place. body part or fracture sites.

The paint is applied with a marker or brush - this operation requires some care. It is not advisable to apply paint in a thick layer, it is better several times, but thinly and accurately. It is best to work in the garage or in the shade, and not "in direct sunlight." If the area is large enough, a sprayer or spray can be used. When painting in this way, be careful not to spray on other parts of your car. To do this, you can use masking tape and old newspapers. After complete drying of the paint, polishing can be carried out.
Many people also apply car polish, believing that such a step will improve the visual quality of car painting. However, under varnish, any difference in color becomes more noticeable, therefore it is advisable to apply varnish only with perfectly matched paint, or not use it with a slight local repair.

6. Special kits for chip removal, for example, using Dr. color chip

According to Dr.ColorChip technology, paints used in local repairs differ in composition from traditional ones. repair kits, selected according to color code car. Dr. Materials Formula ColorChip provides the ability to quickly dry paint, without the use of chambers and other dryers. To remove excess paint, Dr. Colorchip Sealac, which is applied to a cloth and polished by hand until excess paint is completely removed, then the stains from the SealAct solution are wiped off with a microfiber towel.

Everything you need is included. Quite quickly and simply - find out the price of the issue on the Internet. Reviews - various, often do not fall into color. If you choose this option, read more on the forums.

Naturally, from all the above methods and means for removing chips and scratches, you should not expect completely perfect result. But if we compare the price-quality ratio and labor costs, then this is quite effective methods and fit in most situations.

Modern manufacturers produce cars with anti-corrosion treatment bodies with various primers and compositions, improved paintwork. small damage, such as scratches and chips, especially to bare metal, can further provoke serious problems. It is worth asking in advance how to properly tint chips on a car. The services of professional car painters are usually expensive.

You can't prevent small body damage. They appear during operation. Pebbles knock down paint, reagents, saline solutions, moisture accelerate the appearance of corrosion. You can solve the problem on your own. To repair the paintwork easily, quickly, without high costs, you will need a special tint. This is an inexpensive material that does not require special skills or special equipment.

How to tint chips on a car in order to achieve the perfect result? The procedure can be performed independently, and so that the new coating cannot be distinguished from the factory one. It is enough to follow simple instructions.

Diagnostics to detect damage

First, the body must be washed well and wiped dry. As you inspect each component, try to spot defects right away. This will allow you to immediately assess the scale of the work, determine the required amount of materials, and not miss anything. Good lighting is required for viewing. It is best to do this in clear weather.

Choosing the Right Materials

First you need to determine the degree of damage, their scale. The choice of material depends on the nature of the defect:

  • a small scratch or chip - buy a small bottle of tint, along with a degreaser, primer, varnish in the same amount;
  • medium defects, or it is necessary to restore the whole body element- you will need an aerosol can of soil with a volume of 520 ml, paint;
  • significant disadvantages - cans of professional paint, primer, varnish with a capacity of 1 liter or more.

Tints from aerosol cans are no worse than professional ones in terms of characteristics. To choose the color of the material, you should use the VIN code of the car or the paint code. An effective optioncomputer selection shade. It is good if the body has darkened, burned out or been repainted before. If in the latter case an enamel made according to the international RAL standard was used, the process will go faster.


Material application process

To carry out repairs efficiently and achieve a lasting result, you need to use several devices. This is a primer for plastic or metal, degreaser, varnish, paint. If body defects are small, 60 ml bottles are sufficient.

How to paint chips on a car? The sequence of work is as follows:

  • To remove grease, dirt from the surface, you need to apply a degreaser. If you neglect this procedure, you may encounter delamination of the coating. Traces of corrosion are removed with special rust converters or fine-grained abrasives.
  • Deep defects are primed after degreasing - this is necessary for corrosion protection and good paint adhesion. Plastic parts need a specialized primer.
  • The compositions are applied with a special brush. Materials must be distributed evenly. The remains are erased with light movements, with a rag. If several layers are applied, between them you need to take breaks of 15 minutes.

It remains to cover the treated and previously degreased area with varnish. So, it will naturally shine, acquire an aesthetic appearance. Lacquering should be started only after the paint has completely dried.

Polishing

This procedure will help align the transitions between the new and old coating, smooth out uneven areas. Residues that protrude from the surface should be smoothed out with fine-grained abrasives with a hard backing. In the process, the body is wetted with water. Car polish is used to restore shine.

The technology described above will restore coverage and save on the services of specialists. A primer with a degreaser will provide a high-quality, lasting result.


How tint is used

Chips and scratches are not always evident, but their appearance negatively affects the condition of the car. The paintwork has a protective function. deep damage gradually rust, and then their repair will be very expensive.

How to paint chips on a car? The technology is as follows:

  • Examine the surface, evaluate the scale of the work. If the paint layer is not damaged, you can use abrasive polishing.
  • The area to be repaired must be washed and dried.
  • In addition to removing rust, use acid or etch primers. Then, for better adhesion, you need a primer for metal.
  • The cleaned area is degreased. There are tools designed specifically for this.

If in doubt about the safety of a degreaser, or if you are not using a special fluid, test the material first. Apply a small amount to a rag and wipe the most inconspicuous area of ​​\u200b\u200bthe body. Do you see traces of coating on the rag, or notice that it was painted in the color of the car? So, they chose the wrong liquid.

Most the best option- solvent or alcohol compositions. Petroleum products and aggressive solvents will only harm the vehicle.

If you have chosen to apply a bottle of paint with a brush, shake the container well beforehand. With a brush, fill the defect smoothly and evenly throughout the entire depth. Try not to do this for long, because one-component tinting compositions seize quickly.

In modern body coatings, there are no NC enamels. Buy methacrylic or urethane compounds, the use of which involves a two-layer layout. First, a base coat (paint) is applied, then a varnish.

If the kit contains too large a brush, it will not be possible to carefully paint over the defect. It is better to use a different brush, or just cut off the extra villi.

After completion, inspect the treated areas. Poorly painted places are cleaned of the dry coloring composition with solvents or degreasers. Then the painting procedure must be repeated.

While driving on roads, small pebbles constantly fly out from under the wheels of the cars in front, which invariably fall on paintwork your car. As a result, the coating of the car is deformed, becoming chipped.

At first, the deformations are not too noticeable, but after a while everything becomes obvious. Arises reasonable question: Is it possible to somehow eliminate chips without the help of a service station? Answer: you can! Of course, for the restoration process, you will need something, namely: abrasive and polishing pastes, wax tinting pencil (in the color of the car), car shampoo, masking tape (or at least adhesive tape), toothpicks, sandpaper (#2000), rust converter, solvent, auto-marker. In principle, all these ingredients should be in the arsenal of every motorist. And now let's get to work.

1) Take a shampoo and rinse well problem areas cars: those that require repair and let the surface dry;

2) now we analyze the state of the surface. If the paint has chipped off, but the primer has remained in place, then we take an abrasive polishing paste and apply it to the chip. We wait 15 minutes, then carefully polish the place of the chip with a piece of felt. Thus, you will conduct a rough polishing of the problem area. Now apply some thin polish and polish again. What will it give? And you will see for yourself: the place of the chip will be practically (by 90-95%) not noticeable;

3) if the paint came off along with the primer, then do this: put a little paint on the chip that exactly matches the color of your car. Once the paint is dry, apply the abrasive paste first, wait 15 minutes and buff the painted area well. Then apply a thin polish and polish again. The result will pleasantly surprise you;

4) a wax pencil is a great help in eliminating chips on a car body. If the crack or chip is not too deep, then the wax pencil will easily eliminate them. Apply a little wax to the problem area with a pencil, and then polish. It's both fast and simple. however, there is one point: wax is not a very strong substance, so you will have to repeat the polishing procedure from time to time.

How to fix cracks in a car body? (video)

Also very often it helps to solve the problem of chips and cracks special set for touching up chips. It is very easy to use it. Before applying paint to a chip, you should limit the chip area by pasting it around the perimeter with adhesive tape or a piece of masking tape. This way you will avoid accidentally getting paint on the body.

Now take the paints and start picking the color. Do not rush, because in this matter haste is not appropriate. Having picked up the color, apply the paint with a brush. Please note: the paint layer should be thin. The number of layers is three, although it all depends on the nature of the chip. Allow each coat of paint to dry before applying the next. Drips are eliminated with a napkin and solvent. When the last coat of paint has dried, be sure to apply a layer of special varnish, which, after drying, should also be treated with an abrasive and polished with a paste. The surface will shine again!
