Top Coating
Top Coating1. Masking
Mask the area surrounding the damage to protect it from the top coat overspray.
Use masking tape and paper.
2. Spraying top coat enamel / clear coat
Spray 2-3 coats until the intermediate coat is fully covered.
NOTE:
- Do not cover the surface with one heavy coat.
- Apply several thin coats.
- Use the 2-part polyester urethane top coat enamel and a spray gun.
- Mix the top coat enamel with the additive and solvent in the correct ratio.
- Follow the top coat manufacturer's instructions.
After spraying the top coat enamel, allow for 5-10 minutes drying time before you spray the clear coat.
Drying
NOTE: Take care not to let the heat lamp deform the bumper during the drying process.
After spraying the clear coat, allow for 5-10 minutes drying time before you force dry it with infrared lamps or other industrial dryer.
3. Polishing / buffing
- Check that the clear coat has dried thoroughly.
- Wet sand to remove any imperfections.
Use a flexible block, soap, and #2000 sandpaper.
- Using a buffer and compound, remove any polishing marks made from the sandpaper.
Use a buffing sponge, and buffing wool and compounds.

1. Wet sand with #2000 sandpaper and soapy water.
2. Remove moisture using compressed air.
3. Finish using fine compound and very fine compound. Polish with an electric polisher.
NOTE: Polish lightly.
4. Check the finished area at an angle, and make sure there are no polishing marks.
