Bikermouse Posted December 2, 2010 Posted December 2, 2010 Not really a boat-building question, but a boat repair/restoration one. I just picked up a 1967 Cal-20, with hull & fiberglass in generally good shape, but there are some stress cracks topsides and the keel needs to be refaired. My question is, since I'm fairly sure that what I'm looking at is a polyester or vinylester hull, can I use epoxy resin for patching & repairs, or do I need to hunt down the older style resins? I'm sure that there are lots of grey areas in this question's answers, so I'm looking forward to any input. Thanks! Quote
Hirilonde Posted December 2, 2010 Posted December 2, 2010 In theory all 3 resins will work, but epoxy will work best by far. Epoxy adheres to almost anything very well. When in doubt, choose epoxy. Quote
Charlie Jones Posted December 2, 2010 Posted December 2, 2010 Ditto again- just be sure the surface is clean, then go for it. By the way- the the topsides of a boat is twixt wind and water- water line to deck edge. In other words, the sides of the hull. Said with tongue in cheek, sorta. :grin: Quote
