Topcoating

Top Coating

1. Masking

Mask the area surrounding the damage to prevent over-spray of the top coat.

Use masking tape and paper.




2. Spraying top coat enamel / clear coat
Spray 2-3 double coats until the intermediate coat is fully covered.

NOTE:
- Do not cover the surface with one heavy coat.
- Apply several thin coats.

- Use a 2-part polyester urethane top coat enamel and a spray gun.
- Mix the top coat enamel with the additive and solvent, using 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 an 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.

Finish by buffing:




-1. Wet sand with #2000 sandpaper and soapy water.

-2. Remove moisture using compressed air.




-3. Finish using fine compound and very fine compound.

NOTE: Polish lightly.

-4. Check the finished area at an angle, and make sure there are no polishing marks.




-5. Polish with ultra fine compound and a buffing sponge.




-6. Wax the finished area.
