I have recently obtained a 28 ft. 1974 Silverton. In examining the hull I have found very small chips or loose gelcoat about the size of red pepper flakes on the sides not the bootom. Observed closely, I can make out fiber. In one area on the starboard side near the transom there are about 8" to 10" spider cracks. I have never worked with gelcoats and fiberglass before and was wondering what the best repair process / cosmetic repair would be. I will be coating the bottom of the boat as the boat will be in a slip from May to October. Additionally there are spider cracks on the deck and was wondering if a good non-slip paint would work on that area. Any information would be extremely helpful!
