H. Preparing the Surface
1. Saturate a white cloth with acetone.
2. Wipe scratched area with the saturated cloth to remove all
loose debris. If not removed, debris can cause additional
scratches.
C. Removing the Scratch
1. Block sand the scratch with 220 grit sandpaper until
scratch disappears.
2. Wipe the sanded area clean with a white cloth saturated with
water. This step is necessary to prevent large particles of
dust from scratching the gel coat.
IMPORTANT
Carefully observe the scratch while sanding it so that you can stop sanding
immediately when the scratch has been removed. If you are not careful you
might sand all the way through the gel coat and thus have to replace it.
D. Sanding, Buffing, and Spraying
1. Wet sand the repaired area as instructed in Section
6.2, Procedure E, Steps 4 and 5.
2. Buff the repaired area as instructed in Section
6.2, Procedure F.
3. If the gel coat has been sanded through during Procedure C, above
(that is, fiber glass is visible), you must spray the area with a
finishing coat. For the proper finishing procedures see Section
6.4.
