gel coat repair?

[oteps]

I have a couple spots that I want to fix on the gelcoat. The biggest is the size of a pencil eraser. Anyone ever use the small tubes of gelcoat repair stuff?
Or put some fiberglass resin in first with a small paint brush? I figure there was a bubble under it from new making it weaker?

for small stuff get a box of MarineTex two part epoxy filler.
Overfill slightly and sand smooth when it hardens.

I just did a couple stress cracks. ground them out a little and filled & sanded. I used white. Did not bother trying to color match.
I have used it to fill old screw holes too.

There is a trick using packing tape that makes it come out glassy smooth

Oh...it is usually better to sand/grind the hole bigger to get clean surface. Don't fill a dirty hole...

gelcoat is fairly easy to work with, if your using the kit with all the different colors, go very sparingly with the colors trying to match it. Its easy to ruin the whole kit adding too much color to the white. You can mix gel with cabosil, or microspheres to get it to like putty, or you can just dab it on till it fills the hole. The key to gel is to put too much one, that way you can sand back down to the original finish
