Repairing

Though gel-coat is a very durable material, it is susceptible to scratches, blistering, and web-
like cracking (crazing) over time. It is elastic enough to withstand strong blows while flexing
with the hull's movement. Gel-coat problems are cosmetic and will not affect the structural
integrity of your boat.
Some gel-coat 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 gel-coat, can also be acquired through your
dealer. Instructions are included in the patch kit.

OTTOM

AINT

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.

ANVAS

Grady-White’s canvas is made using the highest quality vinyl and latest sewing techniques.

The canvas will not be completely leak proof. The seam holes in your canvas may stretch and tend
to leak. However, you can correct this problem by applying Apseal® or Uniseal™ to the seams.

Please understand that Grady-White does not warrant the fit and design of the canvas to

be entirely watertight.

Maintenance

To maintain your boat's top and other canvas follow these guidelines:

Fabric should be cleaned regularly to prevent the buildup of soil and soil penetration of the
fabric. Simply brush off any loose dirt, hose down canvas and clean with a mild solution and
warm water. Do not use petroleum-based or ammonia cleaners on canvas or clear vinyl as they
will yellow. For heavily soiled fabric, remove from the frame. Soak the fabric in a solution of
1/2 cup (.12 L) of Clorox® and 1/4 cup (.06 L)of Ivory® or Lux® soap per 1 gallon (3.8 L) of
warm water. Let soak until mildew and stains can be brushed out with a common kitchen
brush. Rinse thoroughly with cold water until all soap is removed. Allow fabric to air dry
completely.

Do not steam press or dry in an electric or gas dryer.

This will damage the

canvas fabric. Water repellent was applied to your canvas during manufacturing. The repellent
may have diminished after extended cleaning. Re-treatment of the fabric is recommended. Do
not use wax-based products. Use a water based repellent like Apseal® or Uniseal®.
Scotchguard® is effective for short-term use only.

W A R N I N G

M.E.K.P. (Methyl ethyl ketone peroxide), gel-coat and acetone are flammable and hazardous
chemicals that must be handled properly. Follow instructions carefully. After the gel-coat 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.
