[paulk]

Am in the midst of removing wet (but not rotted, thankfully) balsacore from about a 2'' dia. section of the hull where it has delaminated. We''re working from the inside, so we don''t have to worry about fairing the hull afterwards. In my earlier efforts, we''ve used polyesther (fiberglass) resin with new balsacore and cloth for repairs under the impression that the repair would have the same characteristics as the surrounding structure, which would help to maintain its integrity better. Using epoxy instead of polyester resin it was suggested, would create a "hard spot" in the hull that would end up causing problems later, as the hull flexed and worked around its stiff edges.
I am now hearing suggestions that since epoxy is actually more flexible than polyester, and (as I knew before) is a much better adhesive, expoxy would be the way to go with this new repair. What''s the latest word on this issue?
