Mix a small amount of putty with hardener according to the instructions.
Using a spatula, apply the paste to the area to be treated. By running a spatula over the surface of the putty, level the surface. Do this work quickly enough until the putty begins to harden.
Continue applying thin coats of putty at 20 minute intervals until the level of putty is just above the surface of the bodywork.
When the putty hardens, its excess can be removed with a metal spatula or file. Next, you should grind the area to be repaired with sandpaper, starting with grain number 40 and ending with grain number 400.
Sandpaper should be wrapped around an elastic band, cork or wooden block, otherwise the surface of the putty will not be smooth enough. During grinding, sandpaper should be moistened periodically with water. As a result, a very smooth surface can be achieved.
At the final stage of grinding, the treated area should be surrounded by a ring of stripped metal.
The area to be treated should be moistened with water to remove the dust formed during grinding.
Spray the area to be treated with a thin layer of primer. This will help to identify the flaws made during the putty. Close these defects with a fresh layer of putty and sand again with sandpaper. Repeat the procedure for applying the primer and putty until you achieve the desired result.
Rinse the area to be repaired with water and dry completely.
The area to be repaired is now ready for painting. Paint application should be carried out in a warm, dry, windless place, where there is no dust. If you will be working outdoors, the day should be chosen very carefully. If one body part is being repaired, close parts should be covered. Decorative body parts must also be covered. To do this, you can use duct tape and old newspapers.
Before applying paint, shake the aerosol can well, then spray on a test surface (like an old jar) until the technology is developed. Apply the first thin coat of paint to the area to be repaired. Using 400 grit sandpaper, sand the surface to a smooth finish, then rinse with water and dry. After that, continue to apply new layers of paint.
Spraying should be continued until the required layer thickness is reached. Spraying should be started from the center of the treated area, and, making circular movements, move to the edges, spraying about 5 cm zone outside the treated area. Remove all guards 10-15 minutes after applying the last coat.
New paint should dry for 2 weeks. After that, you should use polishing agents.
