2. Wipe the area to be repaired with a wax/grease remover.

Figure 1:

3. Sand the unpainted area with 400 grit paper and feather about one inch into the painted area, Figure 1. Sand the entire fascia, not just the peeled area.

NOTE: DO NOT USE EXCESSIVE FORCE, JUST ENOUGH TO ROUGHEN THE SURFACE.

5. Check the feathered edge of paint for good adhesion.

a. Carefully slide the edge of your fingernail from the unpainted area to the painted area.


b. If the paint lifts, go back and start again with Step # 3.

7. Tack wipe to remove any contamination.

8. Wipe the area with a suitable anti-static wash solution.

9. Wipe the area with a wax and grease remover using a lint-free cloth.
