NOTE: You must do this procedure on the PP parts of the bumper and side sill panel. Masking Mask the area surrounding the damage to prevent overspray from the intermediate coat. Use masking tape and paper. Spraying top coat enamel Spray the top coat enamel over the surface until the primer surfacer is fully covered. Spray 2~3 coats to get 15~25 microns of thickness. Use the 2-part polyester urethane top coat enamel and a spray gun. Mix the top coat enamel with the additive and solvent, and in the correct ratio. Follow the top coat manufacturer's instructions. Drying NOTE: Take care not to let the heat lamp deform the bumper during the drying process. After spraying the top coat enamel, allow for 5~10 minutes of normal drying, then force dry it with infrared lamps or other industrial dryer.

Polishing Check the top coat enamel has dried thoroughly, then sand the top coat enamel. Use a flexible block and #600~#800~#1000 sandpapers. NOTE: Be careful not to sand down to the primer surfacer. When the painting repair is almost complete, polish the top coat. Use #1500 sandpaper and compound. Material Putty Intermediate Coat Sanding Paint Coat Air blowing/degreasing Use alcohol, a tack cloth, and wax and grease remover. Clean and degrease the surfaces where the masking tape will be attached.
