A. Scratches
6. After the gouge is filled and has dried, sand the
patched area. Begin by using medium-fine grade
sandpaper. Progressively use finer grade sandpa-
per until the surface is very smooth. If necessary,
add filler and then sand the surface again.
Scratches occur during normal use. Below is a step by
step procedure to repair scratches.
1.
Clean area with soap and water.
. Apply a fine rubbing compound and buff.
Wax.
7.
Apply two or three light coats of matching fiberglass
gel coat to the repaired area. Enough gel coat
should be used so that the entire area is covered.

3.
The gel coat must be catalyzed using up to 2% MEK
Peroxide which can be purchased at a supplier han-
dling fiberglass reinforced products. Contact your
Four Winns dealer for assistance.
If this does not work, clean the area and sand lightly with
00 to 600 wet or dry sandpaper and follow with rubbing
compound and wax.

9.
After ample drying time, sand the area using very
fine wet/dry sandpaper. If the appearance of the
area is still not satisfactory, repeat steps 2 through
8 as necessary.
Stress cracks and crazing are the appearance of hairline
cracks in the gel coat surface. When present, these prob-
lems usually occur in the gel coat finish or the outer “skin
coat” fiberglass laminate. The appearance of these
cracks does not pose a threat to the structural integrity of
the boat. In most cases, they are cosmetic and can be
treated.
If above the waterline, polish the area using a fiber-
glass rubbing compound and then wax. If the re-
paired area is below the waterline, the area should
be primed and painted in accordance with the anti-
fouling paint manufacturer’s instructions.
