I was wondering if anyone has used the aerosolized versions of gelcoat to repair hull scratches and blemishes- The kind that come in what looks like a spray paint can. My 89 montauk is in great shape overall, but the front keel edge has worn throught to the green fiberglass underneath in two 1/2 inch sections where the rollers first hit when trailering. Additionally, I do a lot of bay fishing and there are quite a few deep scratches in the keel from the occasional encounter with rogue oysters. None of these go through the gell coat and they only extend back about 4-5 feet. However, everything else from the little ribs on the keel on up the hull is absolutely prisitine so I don't really want to paint the whole bottom. I was thinking of perhaps repairing the scratched and worn areas with one of the epoxies from West Marine and then masking off the hull beneath the ribs and spraying gelcoat as a final finish. I believe that would make a pretty good looking repair. Any comments?

Specktrout - I have not seen spray cans of gelcoat. But I have thought that when the time comes, I would use a tapered spounge brush. They work beautifully with polyurethane - nice smooth coat without brush marks. Try it first though because the gelcoat may have something in it that dissolves the spounge. The cost is minimal so that when you are through, just toss the brush. -- Jerry/Idaho

I've never seen gelcoat packaged in spray cans either, and I would be interested in learning more about the product you've seen - please post more details.

If you fill the indentations with "Marine Tex" and just moisten you finger with "spit,saliva", and just rub the final finish it will be smooth as final epoxy coat,water doesnt give the same finish as saliva for some reason..

I have just finished my entire boat with Mini Craft products. I did use the spray gel-coat it is easy and works great for small uses they also have great matches for boston whaler products.
