washing detergents are usually gentle and are
recommended for cleaning gel coat. Cleaning prod-
ucts such as Ivory or Dawn hand dish washing
liquid can be safely used. Always read the label
before using any product.
Waxing decks, cockpit ﬂoors or other walking
areas is not recommended. Waxing will
produce a very slippery surface, especially
when wet. Wax may also buildup in the skid-
resistant surfaces. Be sure all persons wear
deck shoes while aboard the boat. Footing will
be improved and feet will be protected from
accidental cuts and bruises.
DO NOT use acetone, paint thinner, solvents,
or strong alkaline based detergents, nor
cleaners with a “gritty” and abrasive texture.
Avoid products which contain sodium
phosphate. Common examples of these types
A darkening or discoloration of the skid-resistant
surfac es can sometimes occur as a result of wax
build up. Expo sure to the sun and elements can turn
the wax darker, or occasionally can cause it to
become ﬂaky or powdery. To remove, use ﬁne

There are several products available which are
speciﬁcally designed to clean ﬁberglass exterior
ﬁnishes. Many companies like Johnson & John son
Turtle Wax , etc. manufacture cleaning ﬂuids mild
enough to clean without stripping the wax.
B. Weathering Effects on Gel Coat
Weathering occurs from direct sunlight, water, chemi-
cals, and dust. Some of the terms below describe the
changes that can occur to the gel coat surface.
Treading on a soiled ﬁberglass surface can
severely scratch and mar the ﬁnish. Keep the
ﬁberglass as clean as possible.
Chalking is a result of the gel coat’s top surface being
bro ken down into an extremely ﬁne pow der. When this
happens, the color whitens. The chalk is present on
the surface only.
When cleaning skid-resistant areas, DO NOT attempt
to use a wire brush or sandpaper because this will
remove the skid-resistant gel.
Fading is the uniform change in color. This happens
when the actual pigments have changed color,
especially from excessive chalking, or when the
gel coat has either been stained or bleached by

Blistering refers to a condition in which the unpro-

absorbed water and formed bubbles. See Section
