Blisters on the bottom of my Scot?
Hi Everyone,I bought an old 1969 Scot (#1456) last August and am in the process of restoring it myself. I have read through most of the forums trying to educate myselft the best that I can, but I still have some questions...I have flipped the boat over and have dry sanded (orbital) the many layers of anti-fouling paint off until what i assume is the last layer of paint (red) with some spots here and there from futher sanding of what i assume is the gelcoat. I had planned on repairing all gauges and cracks, some deeper than others) with an epoxy filler, such as Interlux Watertight Epoxy Filler, sanding according to instuctions, then using acetone or Interlux 202 solvent (would perfer to use acetone since it is much less expensive), then applying a primercoat such as Interprotect 2000E and finally toping it with VC Performance Expoxy.My issue is that i am not sure if what i am seeing are blisters or not. I am attaching some photos in hopes that some of you more knowledgable Scot owners will let me know exactally what i am dealing with. There are two big (2-3inch) abrasions that i thought were caused by rubbing, maybe from putting on and off the trailer, but are these actually really bad blisters?? Also, I have read on some forums that the red "paint" I am seeing is acually the gel coat, but I thought the gelcoat was whitish/clear or yellow, which looks as though it is one layer below the red.Once i got down to this red paint and did some reserach, i learned that since i am drysailing the boat, i don't necessarily need to apply anything but fill the bad spots. I called Harry at FS and he confirmed, saying that i could strip the rest of the paint off or just let it wear off over time. I would rather not have to go through the time and $ of painting the bottom if not necessary, but the more i read the more I realize my boat is in worse shape than i had initally thought and i may just have to protect it from further damage.This will be used as a family boat, dry sailed, but I would like to do all the necessary steps to insure that i have done all i can to get this boat back to the best shape possible.Any and all comments/suggestions/advise is greatly appricaited!
