errr... you used a comparison to repairing aluminum with stainless and suffering electrolysis (galvanic corrosion) to make some kind of point about not using epoxy to repair a vinyl ester construction hull. My flippancy was a polite way of highlighting your comparison was bull. As is your statement that using the same materials as original construction is always "logical".

I thought you could put gel coat over epoxy repairs if you remove the amine blush? Not that you'd want to thought - Awlgrip paint or similar can be simpler and quicker than using gel coat - as a professional boat builder and repairer once told me...
