Re: Blisters, OMG
I've never had one but if I found some when hauling for bottom paint I'd spot repair them, just like I would a cracked keel fairing or a grounding ding in the keel. In my view, that's what haulout is for, not just to slap on a new coat of paint.
Way too much is made of blisters - in nearly all cases they are a minor, easily correctable flaw.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
