Elimination of minor scratches that do not affect the metal of the body, carry out in the following order.
Remove loose paint particles by sanding the damaged area with fine sanding paste.
Rinse the treated surface with clean water, degrease and dry.
Apply a thin coat of paint to the scratch with a small brush.
Continue to apply thin coats of paint layer by layer until the surface inside the scratch reaches the level of the surrounding surface of the panel.
Let the new paint cure for two weeks.
Sand the painted surface flush with the surface of the rest of the panel with a very fine sanding paste.
Treat the repaired surface with wax.
If the depth of the scratch has reached the metal surface and caused corrosion, do the following:
- remove rust 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 a solvent and apply it with a rubber applicator (spatula) for a scratch;
- let the putty dry slightly;
- put a cotton glove on your hand, moisten your index finger with solvent and run along the scratch - a slight notch should form on its surface;
- after the putty dries, paint the damaged area.
