CHAPTER 7
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 finish. Use only waxes for
fiberglass and follow the label instructions. Apply a 3' x 3' section at
a time using clean applicator cloths or a buffing 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 efficient 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 fine rubbing compound. Do not
apply 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 factors.
Small air pockets or gouges may also occur through normal wear.
These do not affect the strength of the hull or deck and can be repaired
by yourself, a marine professional or a Regal dealer.
The affected area should be chipped or sanded away and a thin layer
of color matched gelcoat applied. This layer is then sanded smooth
and buffed to its original luster.
