1. Lightly buff the scratched surface with a fine polish to remove loose paint and wax.
2. Rinse the surface with clean water.
3. Apply touch-up paint to the scratch using a small brush.
4. Continue applying thin layers of paint until the paint completely fills the scratch.
5. Allow the new paint to dry for at least two weeks, then blend it with the surrounding paint by buffing the painted area with a fine polishing compound.
6. Finally, apply a top coat of wax to the scratched surface.
If the scratch has penetrated the paint and damaged the metal body, causing rust to appear, a different repair procedure must be used.
1. Remove the rust from the base of the scratch with a pocket knife, then apply anti-rust paint to prevent future rust.
2. Using a rubber or nylon applicator, cover the scratched area with glaze (glaze is a translucent layer of paint).
3. Before the glaze in the scratch hardens, place a piece of smooth cotton cloth around the tip of your finger.
4. Dip the cloth into the thinner, then quickly move it around the scratch surface. This will help you ensure that the surface of the glaze is slightly sunken.
5. Now you can paint over the scratch as described.
Note: If necessary, the glaze can be mixed with thinner to make a very thin putty, which is ideal for filling narrow scratches.
