G. Repairing Hole That Cannot Be Seen
Inside the Structure
1. Feather the area thoroughly with a sanding block and
50 grit sandpaper.
2. Clean the area with a white cloth saturated with
acetone.
3. Cut one piece of fiber glass mat that completely overlaps the
hole (filled with the back up patch of catalyzed resin and
milled fibers) at least 1 inch.
4. Make a mixture of resin and catalyst with a stirring stick in
accordance with the manufacturer's instructions. Mix thoroughly
to prevent uncured spots.
5. On a piece of cardboard, and using a paintbrush, wet out the
piece of mat with the catalyzed resin.
6. Apply the piece of mat over the hole. Remove air bubbles with
the paintbrush and your index finger.
NOTE: Now that the hole has been filled with a mixture of catalyzed
resin and milled fibers, the fiber glass mat has been applied
over the interior and exterior of the hole, the area has been
restored to its original structural soundness.
IMPORTANT
Because the repaired area cannot be seen from inside the structure, it
does not have to be sprayed with gel coat.
H. Repairing Hole That Can Be Seen Inside the
Structure
1. Sand outward at least 2 inches on all sides of the hole
with the power sander and 24 grit sanding disc so that
additional fiber glass materials can be applied. Cup out
the sanded area smoothly so that a smooth, even buildup can
be achieved.
