Ok, So I know this has been covered ad nauseum in the archives, BUT...I couldn't find anything about diagnosing the beginning stages of what a blister condition looks like. Last year I used peel-away to remove about 8 to 10 layers of modified epoxy bottom paint off the hull. I then washed the hull according to the directions on the peel away can, lightly sanded the bare fiberglass with 80 grit (VERY lightly, by the way) and applied 2 coats of ablative bottom paint so I wouldn't have to EVER deal with this again. The boat has been hauled for about 6 months for the winter & I notice VERY slight bumps on the surface of the gel coat where some of the paint has been blasted off from my pressure wash in the fall. The impressions are about the width of a baby pea, and there are ALL over the boat's bottom, quite uniformly. On several of them there is a cross shaped hairline crack in the shape of an "X". Here's my question: Do I have a problem in the making? Thanks in advance, Allen Schweitzer s/v Falstaff C-30 Hull# 632
