CHAPTER 7
Use a mild detergent such as dishwasher powder or liquid. Do not use
automatic dishwasher detergent. Avoid any kind of alkaline cleaners
such as trisodium phosphate (TSP), abrasives, bleaches and ammonia.
For best results use cleaners that are recommended for fi berglass.
WIRE BRUSHES, SCOURING PADS, OR OTHER
ABRASIVE TYPE MATERIALS AND SOLUTIONS
SHOULD NEVER BE USED ON THE HULL
OR DECK OF YOUR BOAT.
THEY CREATE SMALL SCRATCH MARKS
THAT WILL COLLECT MARINE GROWTH
AND OTHER FOREIGN MATERIALS.
It is recommended that you wax the gelcoat surface twice yearly to
prevent loss of gloss and to protect the fi nish. Use only waxes for
fi berglass and follow the label instructions. Apply a 3’ x 3’ section at
a time using clean applicator cloths or a buffi ng bonnet. When a haze
develops, use a power buffer at low speeds (1200-2000 rpm) to remove
the haze. Keep the buffer moving to avoid heat buildup. The power
buffer is very effi cient at removing contaminants from gelcoat. Never
wax gelcoat in the direct sun.
When the washing and waxing as recommended does not restore the
shine it may be necessary to use a fi ne rubbing compound. Do not ap-
ply rubbing compound in direct sunlight. A power buffer at low speed
does an excellent job to remove impurities from the gel coat that cause
dulling. Use light pressure and keep the buffer moving. Re-wax after
compounding to buff the surface.
“Hairline cracks” or “spider webbing” could develop in the gelcoat
surface of a hull or deck. This can be caused by impact or other fac-
tors. Small air pockets or gouges may also occur through normal wear.
