Avoid working in direct sunlight. This dries out the
wax or compound, and can stain the surface.
use either denatured or rubbing alcohol. If this does
not work, consult your Four Winns dealer for profes-
sional assistance.
Use clean pads or cloths to apply a thin coating
of wax or rubbing compound to a small area such
as three feet by three feet. Remove any excess,
and then rub the area with a buffing pad, or
power buffer. Apply pressure only as necessary
to restore the surface finish. Applying too much
pressure or buffing in one place too long can
permanently damage the surface.
NOTICE
DO NOT use acetone, ketone, or other
solvents to remove stains. These chemicals
are flammable and may damage the gel coat.

After applying compound, always follow with
waxing.
Fiberglass is one of the most durable, strong, and
forgiving construction materials afloat. It is resilient
and normal repairs can be made without affecting
the strength or structural integrity of the boat.
NOTICE
If using a power buffer, use a low RPM buffer
with light pressure. Keep the pad wet and
the buffer moving at all times to prevent heat
build up.
Striking docks, other boats, or submerged
objects could create a very hazardous situ-
ation or severely damage the fiberglass. In the
event an object is struck below or near the
waterline, proceed directly and cautiously to
the nearest service facility and remove the
boat from the water. Closely inspect the hull
for damage. If the outer fiberglass laminate
was penetrated, repairs must be made prior
to relaunch.
NOTICE
When sanding, DO NOT use a power or belt
sander to prevent gouges, uneven areas, or
other damage. For best results, block sand the
gel coat.
C. Stains
Stains can appear anywhere on the exterior of the
boat and may be a result of contact with tar, plant sap,
leaves, rust from metal fittings, and other materials.
Surface stains may be removed with hand dishwash-
ing soap, mild cleansers, or some household deter-
gents. DO NOT use chlorine or ammonia products.
These products can affect the color of gel coat.
Commercial car washes use strong cleaners and
should be avoided.
Occasionally, blisters, crazing, scratches, or damage
to the fiberglass can occur. Repairs may be necessary
to correct the problem.
