While I agree that the osmosis issue is overblown, I'd be suspicious of those "paint blisters" he identified. We suspected paint blisters for the bumps that we had circled before they collapsed. But when the paint was removed there was a discolored outline in the gel coat that suggested they were actual blisters. Impossible to tell for sure until the paint is removed and some investigative grinding is done. And unless all of the bottom paint is stripped, it's virtually impossible to identify all of them. We chased individual bumps after three winter haulouts before finally biting the bullet and stripping off all the bottom paint for a detailed inspection and comprehensive fix. Incidentally, there was a 42 Tug next to us undergoing a blister repair/epoxy bottom job when were doing the final fix on bros boat. Endemic to the breed, apparently.
