Re: gel coat repairs
Paraman-
Almost forgot.....before you spray on gelcoat.....you need to sand entire area around repair with 180 grit. This will give some bite for the gelcoat to adhere to but will also buff out if you don't spray over everything you sanded.
Once gelcoat is cured (depends on temperature and humidity).....wait a couple of days....you'll need to wet sand the repair area with some 600 grit, and then 1000 grit. After that is done....buy yourself some gelcoat buffing compound (it is a white paste....the regular red liquid buffing compound is more for paint but does work) and start buffing. Use heavy pressure at first and then gradually lighten up and allow the pad to polish the surface.Be sure to dress (clean) your buffing pad often.
As far as using gelcoat to fill in spider cracks...I wouldn't because they will most likely come back. If the cracks are fairly small....you can use fiberglass putty (yellowish/green with bits of glass mixed in)instead of the strands from the 24 ounce roven.
Hope this helps.
