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 the spatula over the surface of the filler, level the surface. Do this work quickly enough until the filler begins to harden.
Continue applying thin coats of filler at 20 minute intervals until the filler level is slightly raised above the body surface.
When the putty hardens, its excess can be removed with a metal spatula or file. Next, sand the repaired area with sandpaper, starting with grain number 40 and ending with grain number 400.
Sandpaper should be wrapped around a rubber band, cork or wooden block, otherwise the surface of the putty will not be smooth enough. During sanding, the sandpaper should be periodically moistened with water. This will help achieve a very smooth surface.
At the final stage of grinding, the area to be treated should be surrounded by a ring of cleaned metal.
The area to be treated should be wetted with water to remove dust formed during grinding.
Spray the area to be treated with a thin layer of primer from a spray can. This will help reveal the imperfections made during the filler. Fill these defects with a fresh layer of filler and sand again with sandpaper. Repeat the procedure of applying the primer and filler until you achieve the desired result.
Wash the area to be repaired with water and dry completely.
The repaired area is now ready for painting. The paint should be applied in a warm, dry, windless place where there is no dust. If you are working outdoors, the day should be chosen very carefully. If one body part is being repaired, the nearby parts should be covered. Decorative body parts should also be covered. For this, you can use adhesive tape and old newspapers.
Before applying paint, shake the can well, then spray a test surface (like an old can) until you develop the technique. Apply a first thin coat of paint to the area to be repaired. Sand the surface smooth with 400 grit sandpaper, then rinse with water and dry. Then continue applying new coats of paint.
Spraying should be continued until the required layer thickness is achieved. Spraying should begin from the center of the area to be treated and, making circular movements, move toward the edges, spraying approximately 5 cm beyond the edge of the area to be treated. Remove all protective equipment 10-15 minutes after applying the last layer.
The new paint should dry for 2 weeks. After that, polishing agents should be used.
