Thanks for input & interesting approaches. Am still interested in hearing more about the compatibility /flex issues between polyester resin and epoxy resin in the same hull. It was presented to me as an important item by a professional several years ago, and I don''t want to dismiss it based on a single response to the effect that it''s not rocket science. (It''s MY BOAT, after all!) On a wooden boat, a builder wouldn''t repair a douglas fir hull with a teak plank; the stiffer teak would make the other parts flex around it, and lead to more leaks and problems in the long run. Is this comparison valid with different resins?
