Since the water buildup probably occurred over a long

were...popping off the gel coat?

That is probably a very real concern in my opinion. Turning water
into steam can create some very high pressures if entrapped.

The best cure is simply not to buy a boat with an osmotic blister
problem. I know this flies in the face of the advice of boat salesmen,
owners of boats, and others with a stake in the used boat business, but
better osmotic acne remain *their* problem, and not yours.

Easy to say but the real world is different if you own an older boat.
Boats that have never blistered in the past can suddenly develop a
crop if conditions change, e.g., water temperature, length of season,
etc. On a boat over 4 or 5 years old you really have no recourse with
the manufacturer.
