Elimination of traces of small scratches that do not affect the body metal should be carried out in the following order. Remove particles of loose paint by treating the damaged area with fine sanding paste. Rinse the treated surface with clean water, degrease and dry it.
Apply a thin layer 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.
Allow the new paint to fully cure for at least two weeks.
Sand the transition surface flush with the surface of the rest of the panel using a 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 composition to prevent further development of corrosion deep into the metal;
- dilute the putty slightly with a solvent and a rubber applicator (spatula) put it on 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, while a slight notch should form on its surface;
- after the putty has dried, paint the damaged area (see below).
