I have some small blisters since I purchased me 1985 Maramu 7 years ago. I've always been told that they were small and just cosmetic.
This latest haul out in NZ I'm being told that I should have a complete osmosis repair and it could take 2 1/2-3 months for the hull dr dry out after grinding and before 3 coats of epoxy can be applied. The cost is estimated to be $25,000 nzd.
My question to other Maramu owners is, is this a common problem with older Maramu's? Has anyone with a similar problem taken a different approach (like grinding the blisters individually yourself vs using a me jibe to skim off the entire chop layer of fiberglass.
