STRUCTURAL REPAIRS (Cont.)
FIBERGLASS TOUCH-UP AND SURFACE REPAIRS
1. Remove wax, oil and dirt from around damaged area with acetone, Methylethylketone or equivalent
and remove paint to gel coat.
2. Damaged area may be scraped with a fine blade knife or a power drill with a burr attachment to roughen
bottom and sides of damaged area. Feather edge surrounding scratch or cavity. Do not undercut edge.
(If scratch or cavity is shallow and penetrates only surface coat, continue to step 8.)
3. Pour a small amount of resin into a jar lid or on a piece of cardboard, just enough to fill area being
worked on. Mix an equal amount of milled fiberglas with resin, using a putty knife or stick. Add
catalyst, according to kit instruction, to resin and mix thoroughly. A hypodermic needle may be used
to inject gel into small cavities not requiring fiberglas millings mixed with gel.
4. Work mixture of resin, fibers and catalyst into damaged area, using sharp point of a putty knife or stick
to press it into bottom of hold and to puncture any air bubbles which may be present. Fill scratch or
hole above surrounding undamaged area about 1/16 inch.
5. Lay piece of cellophane or waxed paper over repair to cut off air and start cure of gel mixture.
6. Allow gel to cure 10 to 15 minutes until it feels rubbery to touch. Remove cellophane and trim flush
with surface, using a sharp razor blade or knife. Replace cellophane and allow to cure completely for
30 minutes to an hour. Patch will shrink slightly below structure surface as it cures. (If wax paper is
used, ascertain wax is removed from surface.)
7. Rough up bottom and edges of hole with electric burr attachment or rough sandpaper. Feather hole into
surrounding gel coat, do not undercut.
8. Pour out a small amount of resin, add catalyst and mix thoroughly, using a cutting motion rather than
stirring. Use no fibers.
9. Using tip of putty knife or fingertips, fill hole to about 1/16 inch above surrounding surface with gel
coat mixture.
ly cured.
11. After trimming patch, immediately place another small amount of gel coat on cut edge of patch and
cover with cellophane. Then, using a squeegee or back of a razor blade, squeegee level with area sur-
rounding patch, leave cellophane on patch for one or two hours or overnight, for complete cure.
12. After repair has cured for 24 hours, sand patched area using sanding block with fine wet sand- paper.
Finish by priming, again sanding and applying color coat.
FIBERBLASS FRACTURE AND PATCH REPAIRS
1. Remove wax, oil and dirt from around damaged area with acetone, methylethyketone or equivalent.
2. Using a key hole saw, electric saber saw, or sharp knife cut away ragged edges. Cut back to sound
material.
3. Remove paint three inches back from around damaged area.
4. Working inside structure, bevel edges to approximately a 30 degree angle and rough-sand hole and
area around it, using 80-grit dry paper. Feather back for about two inches all around hole. This roughens
surface for strong bond with patch.
