Scratches on a car body are quite common. You can find them anywhere, unsuccessfully opening the door, parking too close to a bush, not noticing an obstacle, and in a number of other situations. In some cases, you can get rid of them only by resorting to painting in the cabin, in others - polishing scratches on the car with your own hands.
Types of scratches
If the damage appeared on the plastic part of the car, then there is no particular cause for concern. But deep scratches on the metal can lead to corrosion. They are conventionally divided into several types:
- violation of the integrity of the top layer of varnish;
- damage to the enamel layer;
- scratch on the body to the ground;
- deep damage to the metal.
Such defects are usually determined "by eye". Then, depending onthe degree of damage, a decision is made how to remove scratches on the car, certain materials are selected. If the defect does not touch the ground, it is classified as shallow. If, nevertheless, the integrity of this coating is broken, the scratch is classified as deep.
It's understandable that a little damage is much easier to deal with. Sometimes it is enough to treat the surface with a special compound or wax. Very often, car owners resort to exposing the body with a special machine to polish minor scratches on the car. Deep defects are eliminated by working to the base, followed by painting with a restoration pencil designed for this purpose.
What to choose, paste or gel?
In addition to the technology itself, the choice of means for polishing is of great importance. Having mastered the basics of the production process, it is necessary to choose protective and restorative compounds. Polishing pastes are usually divided into two categories - powder and gel.
In the first case, the paste is chosen for a metal coating with numerous scratches and chips. Polish the surface at each stage, reducing graininess. Gel funds are weaker. They are used to treat soft paintwork with little damage.
Gels and aerosol pastes in cans can be used for different parts of the body. The first ones are applied to the polishing wheel for work, in this way it is convenient to process vertical surfaces (body wings, doors). Aerosol paste is sprayed on the roof, hood, trunk andrub to remove damage.
The use of fine abrasive paste cannot be permanent. After each application, a thin layer of paint is destroyed. If you treat the surface constantly, after a year the paintwork will be erased. In the same way, abrasive polishing of the body after repair or coating work is carried out. The main goal is to eliminate smudges, roughness, leveling the outer layer.
How to polish scratches on the car with your own hands, which turned out to be deep, but polishing with a machine did not fix the problem? Then a recovery pencil will come to the rescue, it will simply sketch the damage.
If the scratch is narrow and reaches the ground layer, take the following actions:
- the damaged layer is cleaned and dried, after which it is treated with white spirit;
- then, a wax pencil is distributed over the surface of the defective area in a circular motion;
- finish it thoroughly with a soft microfiber cloth.
To fill a large and deep scratch, it is recommended to use a restoration pencil. It contains acrylic paint. The product penetrates deep into the coating, restores the scratched area and protects against corrosion. In addition, the result is a more aesthetically pleasing surface.
When choosing a restoration pencil with a specialattention should be approached to the selection of shade. The damaged area is thoroughly washed and dried. Then sandpaper removes rust and remnants of the material that caused damage. Next, the surface is degreased with white spirit. If the scratch is so deep that metal is visible, it is pre-primed with a special tool that can be purchased at any auto shop.
The defective area is primed, and after the layer has dried, they begin to paint over the scratch. The pencil is well shaken and spread over the surface with a brush. If an additional layer is needed, it can be applied only after the first one has completely dried. To protect the restored area, an additional colorless varnish is applied.
