Finish/Waxing

Gel-coat will age or dull naturally due to constant exposure to the natural environment and
pollutants. Discolorations are shallow in depth. Factors that will affect the rate of
discoloration are: the sun, pollution, old wax accumulation, and the salt content of water.
Polishing compound (fine abrasive) or rubbing compound (coarse abrasive) is recommended
for use on fiberglass finishes to remove scratches and stains or restore severely weathered
surfaces. These products can be applied by hand or mechanical means. The process below will
help restore fiberglass finishes:
•Clean the affected area with a good detergent.
•Remove stubborn stains or discoloration by gently wet sanding the affected areas with 600
grit "wet or dry" sandpaper. ALWAYS SAND IN ONE DIRECTION. Use plenty of
water and sand curves in the same direction. Dry the area to make sure all the discoloration
has been removed. Repeat this process if necessary.
•Buff using a polishing compound suitable for fiberglass, an electric buffer (1750-1800
RPM), and an 8-inch lamb's wool pad.
Keep buffer moving. Do not allow it to rest in one spot. Heat build up will quickly distort the
surface.
Compounding too often or excessive compounding can wear away the gel-coat.
•When buffing is complete, wash away compound with clear water and dry the area.
•Once the area is clean it may be waxed. This will enhance the gloss while providing a seal
to retard staining or soil accumulation.
•See a local dealer for advice on wax for your boating region. The wax film will seal the
pores as well as enhance the looks of your boat. DO NOT wax surfaces that may be
walked on; they will become slippery. While waxing your boat, inspect the surface for
any damage. Have the damage corrected as soon as possible.
