- Before plastering the car with your hands, degrease it. Usually, when washing and wiping, you will be able to assess the front of the work and detect other small body defects.
- Start sanding, the purpose of which is to level the surface, removing excess paint from it, rust. Stripping of the necessary site is carried out by a grinder or sandpaper. To begin with, the car is treated with coarse sandpaper, and then - fine-grained. Prepared ??thus, the car surface is an excellent base for applying primer and paint. Although the desired area should be ground to bare metal, don't overdo it, trying to achieve surface gloss - it will not be needed at this stage.
Grinding the car body with a grinder
- Next, the car putty involves cleaning from dust, formed at the previous stage. It should be wiped with a clean cloth, but do not wash - contact of bare metal with water will nullify your previous efforts, causing corrosion. To obtain a smooth surface before the next stage, you can treat the car with degreaser. This measure will allow a layer of putty on plastic or metal to stay securely on the surface, so that in the future you do not complain about it, that it quickly cracked or flaked off.
Preparatory activities provide more 50% success in working with putty. In turn, applying the composition with your own hands, according to technology, on the most polished and degreased body regardless of quality of a first coat or paint can provide them with more durable adhesion.

spackling
The spackling process can be divided into several stages:
- Before applying putty, it must be diluted to the consistency, indicated on the package. One composition can treat the surface in its original form with the addition of a hardener, and others - diluted with solvent, which can be sold as a set or separately. This allows you to apply the mixture with a spatula or spray - as you see fit. The composition does not lose its performance properties.
- After dilution, apply the starting material on a spatula or prepare a spray gun and apply it to the repair area of the car body.
- Perform the procedure 2-3 times, until the area is completely filled with material and leveled relative to the rest of the surface. Keep in mind, what you need to take breaks in applying the material - how long it dries, indicated on the package (usually, at temperature +20 it happens for 20-30 minutes).

- Before each stage of application, dilute the composition again - due to the presence of hardener in the two-component composition, it will dry regardless of the room temperature. 5-7 minutes.
- Grind the composition coarse-grained, and then fine-grained abrasive (sandpaper). To prevent damage to the damaged areas of the car, insulate them with film and masking tape.
- After obtaining the desired result, treat the surface of the car with a finishing composition.
After applying the finishing composition, you can once again walk on the surface with fine-grained sandpaper. Then - do the primer and paint the car.
