To remove traces of minor scratches that do not affect the body metal, perform the following procedure. Remove particles of peeling paint by treating the damaged area with a fine grinding paste. Rinse the treated surface with clean water, degrease and dry it.
Apply a thin coat of paint to the scratch with a small brush. Continue applying thin coats of paint, layer by layer, until the surface inside the scratch reaches the level of the surrounding panel surface.
Allow the new paint to fully cure for at least two weeks.
Sand the transition surface flush with the rest of the panel using very fine sanding paste. Treat the repaired surface with wax.
If the depth of the scratch has reached the surface of the metal and caused its corrosion, then:
- remove corrosion products with a scraper;
- treat the surface with an inhibitor compound to prevent further development of corrosion deep into the metal;
- dilute the putty slightly with solvent and apply it to the scratch with a rubber applicator (spatula);
- let the putty dry slightly;
- put a cotton glove on your hand, wet your index finger with solvent and run it along the scratch, this should create a slight indentation on its surface;
- after the putty has dried, paint the damaged area (see below).
