In article .com, "Skip Gundlach" wrote: The plot thickens (like epoxy in hot weather)... Our boat is covered in poorly repaired blisters. I don't know how, if you hauled the boat for survey and had any kind of competent surveyor you got a boat that you didn't know was blistered When we bought our boat it was 20 years old. The PO had peeled the bottom and put on 20 coats of epoxy IIRC. When we hauled it for the survey, the surveyor said there were 'cosmetic' blisters - he pointed them out to me, and I saw them. We decided to do nothing. We've never seen the blisters again. The max we've seen are a couple around the waterline at the edge of the epoxy coat. We've always had the boat either red or blue (alternatively), because we heard that whales don't like black hulled boats or another color that I can't remember what it is. Dang! It's always something, isn't it? I'd review http://yachtsurvey.com/blisters.htm (again) before you continue. Our 35 year-old non-epoxy is still fine, and epoxy has serious drawbacks. Because you already have a reveal coat, I'd stick with the current color. No need to get confused whether a patch is the first or second red layer. And don't scuff for adhesion -- since there's not much to be had, it IS intended to be ablative and the fresh coat will chemically etch and bond -- but only slightly for roughness. No need to remove stuff that's still good. |
