I must say this forum is a wealth of knowledge and experience and appreciate the comradery. I am currently restoring a 67 and 71 Sunfish. The 71 is mint the 67, not so much. The 67 I have blind patched hull holes and found the gelcoat was shot meaning lots of little fine pock craters encompassing entire hull. I plan to sand down, fair it all, sand out, acetone then the big question, to paint or gelcoat.
