I have perhaps thousands of tiny pimple sized blister near the waterline - they only extend down maybe a couple of inches along the majority of the hull, and a couple of square feet at the bottom of the hull in the stern area. From the above postings, it sounds like my boat has a gel coat adhesion problem, at least in these areas.
There are also, perhaps 50 dime sized blisters on the bottom.
The surveyor tapped out the hull and said the bottom is sound throughout.
To remedy this, would it be best to get a yard to peel the gelcoat off, then do spot repairs on the dime sized blisters and then epoxy barrier coat? Ideally, I would have it peeled down to where there is no more evidence of hydrolysis (sp?), then lay on mat and finally barrier coat it, but I'm looking to see if there is an effective economical way of fixing the blisters.
One thing about the first method is that substantial drying out time would be involved I suppose. However, if you peel down past the hydrolyzed layers, would drying out still be required?
FYI, the boat is a Hotfoot 27, built in 1982 - if that is any help.
