I have started to sand into the hull, using a small belt sander. The ridgid mentioned in this thread. So far so good, it is small enough that I have enough control to not make a mess of things and it's dust collection is working well. At this point it is more exploratory work than a full hull strip. None of the areas are blisters, just areas that look like the epoxy has been compromised. For the most part things look dry but I am finding some pitting into the hull;
Can anyone tell me is this the result of a flawed layup at build time or a result of osmosis/hydrolysis?
After sanding I flush with water, let dry then wipe with acetone, a day later the pits are dry.
