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
4 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 do 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.
