My jaw hit the floor.
Sure enough, they used a grinder and ground down their 36 year old boats bottom only where the blisters lay, let them sit for a few days then filled them in lickity split, painted with barrier coat and new bottom paint
and they were down in Miami
before I could even get my jaw off the dirt. All by themselves and they weigh maybe 200 pounds between them.
Basically, he explained to me that 99% of blisters are just cosmetic and he never bothers to go through the blister repair. I've heard the same from a lot of people.
Yep, I've done this (or similar)and know many who have. There are three camps and neither is wrong IMO.
*One camp would peel the whole boat, probably spend at least 6 months out and spend 5 figures on a new bottom. They may not even reapply more fiberglass
when doing this. Most the peeling I've seen takes 1/8 to 3/16 of material off. That may be 10-15% of hull
thickness depending on the boat. On many boats this is OK, but some boats are not as thick as you might imagine!
*The other camp does as mentioned above by the in the quote. Grind them out, wait for any wet rings to disappear, fill and epoxy
*The last camp grinds them out, removes all paint
, wait for any wet rings to disappear, fill and epoxy
coat the whole bottom.
I've done all 3. Still undecided.
