303 FOR FIBERGLASS: Never bu
ff
or wax again! Like vinyl, gelcoat
fi
berglass (polyester resin) is a UV-sensitive plastic.
Though manufacturers add UV stabilizers to vinyl and gelcoat
fi
berglass in the manufacturing process, these protective
agents weaken over time and must be replenished if continuing UV protection is desired. Colored gelcoat
fi
berglass is
particularly sensitive to UV degradation, and 303 Protectant is by far the easiest way to make colored
fi
berglass look like
new again, and to keep it that way.
303 Protectant works by penetrating to restore like-new color and gloss. Spray on enough 303 to thoroughly wet the
surface (303 goes farther if it’s sprayed on and then rubbed around & in). Wipe away excess with a soft, absorbent cloth.
Wipe until completely dry, changing cloths as they become damp. Unlike wax, 303 is not left to dry before it is wiped o
ff
. If
303 has dried on the surface, it is easily removed by spraying the area with more 303, then wiping dry.
For best results, apply 303 out of direct sunlight so
fi
berglass surface is not overly warm. A hot surface causes 303 to
evaporate before it can do its job. About 2% of the time, prebu
ffi
ng (compounding) is required. When required, be sure
to use a rubbing compound that does not leave a coating or sealant. Use pure rubbing compound with only the
fi
nest
abrasive.
REAPPLYING:
Reapply by spraying 303 on the surface and wiping dry with a soft, absorbent cloth...very
much like dusting furniture, and just as easy! Mist it lightly
fi
rst with 303, then towel dry...takes an extra 30-
40 seconds. This is an excellent way to keep up the UV screen and totally prevent UV caused slow-fade.
WHEN TO REAPPLY:
303 is water-repellent (beads water). When the water repellency begins
to diminish, it’s time to reapply. If you think it may be time to reapply but don’t know for sure,
test small spot with 303. If any of the color or luster comes back, reapply. Usually, a simple
spray on/wipe o
ff
reapplication for every 30 to 80 days of exposure is su
ffi
cient.
DOES 303 ALWAYS WORK?
303 always works unless there is something on the surface keeping
303 away from the
fi
berglass: te
fl
on, silicone, polymer sealants or fresh wax. If the surface
has been freshly waxed, it is not necessary to remove the wax; Just wait a few weeks and try
again. Wax does not last long enough to warrant the e
ff
ort required to remove it.
OLDER SURFACES
: Even after a few years without care, it may be unnecessary to compound before using 303.
To
fi
nd out for sure,
fi
rst apply 303 normally. If this does not restore the like-new color and gloss typical with
303, try this: In the shade (or just before dark), spray a basketball-sized spot with 303. Rub it in and spray again
to make sure the spot is thoroughly wet with 303. Let set for a few hours or overnight. Spray the spot again
with 303 and wipe dry. This is often all it takes to make gelcoat look like new again without compounding.
