Blisters have always been a problem for my hands. For the past few years I just sanded and repainted the bottom. I pulled the boat this fall to do a refit and decided to tackle the blisters (many). Blisters were only in the gel coat, not into the fiberglass. I was first planning to dig the blisters out, fill, and then heavy sand before barrier coat. Then it was suggested I soda blast, so I got prices for that. Then my surveyor suggested I peel the bottom and get rid of all the blisters. Glad he did. Peeling was cheaper than soda blasting and a whole lot easier than sanding. I still have to grind the areas the machine couldn't get to but all blisters are gone. Will be building up with epoxy and go from there. A lot of work to go but I got rid of all the blisters. Letting the bottom dry til weather allows for epoxy. Just my pennies worth.
