Seems to me that if you avoid painting the gelcoat, you avoid getting peeling later on.
I used it on my Catalina 27 and it held up for about 3 years. It took several applications, though, to completely fill the cracks. Once filled, then polished with rubbing compound and a couple coats of wax it looked great.

sailingdog Like painting anything, 95% of the work is in proper surface preparation. Do this, then the job will look great...don't do this then the job will look like crap and not last.

Cottonmouth Its one of those I'm not sure if I should, not sure if I shouldn't things. Ive painted everything from cars to motorcycles to houses I think if I research it enough it will work out with no peeling or problems.

chrisncate Paint for sure. A good paint job is well worth the effort and looks great.

Cottonmouth Thanks everyone for the input as they are not structural cracks I will figure out if I should paint at all.

I'd point you to this basic article on gelcoat cracking and how to tell what it means that I wrote a while back. If the cracking is just crazing, then sanding, fairing and painting is a good solution. If it is caused by stress, reinforcing or repairing the area is a necessity before doing anything else.

If you have to repair the area, using epoxy instead of polyester or vinylester resin makes more sense, since it is often easier to use, especially for novices. You can gelcoat over epoxy, or you can paint it. In any case, it needs to be protected from UV by some sort of finish. Gelcoat will require less maintenance in the long run.

71Irwin32 I just did mine and took off the gel coat, not for the same reason, but due to lots of pitting. I guess you'd need to understand why you got all the "spidering".

I used 4 barrier coats directly on the bare fiberglass and can't really tell the difference in the finish, but know that the fiberglass is well sealed.

You can check all the videos on my website.....and get an idea of what it looks like.
