Would it be a total FAIL if I laid up a small strip of fiberglass over 3m 5200? I found a scrape in one of the side runners on the hull that was letting in a small amount of water, I'd need to pump it out every 1/2 hour or so. Anyway, the scrape is about 5" long & 1/4" wide (not very big), I used 3M 5200 & it took care of the leak, problem is whenever I pull the boat out of the water it rubs some of the 5200 off on the bunk & I need to dab some more on there for the next outing. Do I need to remove the 5200 if I want to glass over the scrape or can I just glass over it? I know the proper way is to clean the surface completely, but for such a small repair I was hoping to get away with just a quick cover over.
