The repair systems contained in this bulletin are recommended as a guide when repairing basecoat/clearcoat exterior finishes on the above styles.
The following procedures outline a method for making spot/partial and full panel repairs on nonflexible parts and full panel repairs on flexible parts.
Nonflexible Panel Repair System
Basecoat - Lacquer or Enamel
1.
Wash with a mild detergent and water to remove any water soluble contaminates, then clean with wax and grease removing solvent to remove any
tar, silicone or other road film not removed with the detergent wash..
2.
Repair and featheredge damaged area(s) as required.
3.
If substrate is metal, treat surface with a metal conditioner and conversion coating according to label directions. Allow to dry thoroughly and
apply primer-surfacer to repair area. Allow to dry 20-30 minutes before sanding.
4.
Using wet or dry #400 grit sandpaper or finer, sand entire area(s) to be refinished with the basecoat color. Areas to be clear coated only, should be
wet sanded with #600 or finer sandpaper or hand compound (follow manufacturers' recommendations).
5.
Reclean panel(s) with wax and grease removing solvent and then tack wipe.

6.
Apply one or two coats of adhesion promoter within moldings and/or breaklines of the panel section(s) to be refinished. When making paint
repairs to areas such as quarter panels where the repair is not confined within moldings or breaklines, apply adhesion promoter a minimum of 4-6"
onto adjacent panel. Adhesion promoter must extend beyond the area to be covered by the clear coat when not confined by moldings (Figure 1).
Allow to flash a minimum of 30 minutes before applying base color coat. Some enamel basecoat may not require adhesion promoter. Follow
manufacturers' recommendations.
