Repairing
Though gelcoat is a very durable material, it is susceptible to scratches, blistering, and web-
like cracking (crazing) over time. It is elastic enough, however, to withstand strong blows
while flexing with the hull's movement. Gelcoat problems are cosmetic and will not effect the
structural integrity of your boat. Some gelcoat damage and imperfections such as nicks and
scratches can be repaired by obtaining a color match patch kit. This kit can be purchased
through your Grady-White dealer. Acetone, the most suitable cleaning agent for gelcoat, can
also be acquired through your dealer. Instructions are included in the patch kit.

If your boat is left in the water for more than a few days at a time, the hull bottom below the
waterline should be painted with anti-fouling paint to protect it from marine growth and barnacles
that hinder performance. Since anti-fouling paint slowly dissolves, yearly inspection and cleaning
of the hull bottom to prevent marine growth is advised. Repaint when necessary. To help prevent
blistering, use an epoxy barrier coat to be applied in conjunction with the anti-fouling paint.

PHOLSTERY
Your exterior vinyl upholstery may be cleaned with a mild solution of household detergent
and fresh water. Commercial cleaners for vinyl also work well. Since the seams of your exterior
upholstery are not waterproof, your upholstery should be stored in the cabin or covered when not
in use. Exterior cushions will trap moisture between themselves and the gel coat. If a cushion is
not removed to allow the moisture to dry, blistering of the gel coat may occur. Cockpit bolsters
may be removed if you desire. These bolsters clip onto brackets mounted to the deck structure.
Set screws are then installed through the underside of the bolster to hold them in place. Most
cabin cushions are removable and may be dry-cleaned. Some cabin cushions are of a Herculon-
type fabric and may be cleaned with upholstery cleaner.

Duratrim and polyethylene are used for toe rails, trim, cutting boards, lids etc. Maintenance of
your duratrim should include regular cleaning with soapy water. Apply a surface protector at least
twice per year. Polyethylene can be cleaned with products such as 409 or any spray and wipe
cleaner. Plexiglas, used to cover your instruments radio box and also as interior storage doors, can
be maintained by use of a glass cleaner and a soft cloth.

M.E.K.P. (Methyl ethyl ketone peroxide), gelcoat and acetone are flammable and hazardous
chemicals that must be handled properly. Follow instructions carefully. After the gelcoat is
catalyzed, it will soon heat up and put off fumes. When finished with catalyzed chemicals, or if
they start to build up heat, submerse completely in water until cool.
