SEQUENCE OF WORKS
1. Clean damaged areas thoroughly with gasoline or solvent.
2. If your car has paint from another car on it, polish the area thoroughly with polishing cotton, polish or cleaner down to the top coat. The polishing area should be as small as possible.

Fig. 3.16. Removing small and large scratches with sanding paste or paint cleaner when the top coat is not yet damaged
Small and large scratches can be removed with abrasive paste or paint cleaner when the top coat is not yet damaged (Fig. 3.16). Use only high-quality material from specialized stores.
3. Carefully sand the torn edges of the scratch with a small strip of fine-grained sandpaper (grain size not less than 800) using water. Constantly wet the sandpaper and pour water on the sanding area. Do not remove the topcoat.
4. Then polish the damaged area with a soft polish. This will distribute paint particles from the adjacent paint layer into the scratch.
5. Cover the treated area with a preservative.
6. Finally, polish the entire car if desired.
