Coring materials

Epoxy will stick to a cured polyester but polyester will not stick to epoxy that is cured. I have been doing lots of it lately.

80 kg foam is a bit light in hull bottoms. Ring around all the reputable professionals and tell them your poly/vinyl boat needs repairing. Then ask which resin they would use. The only ones that will say epoxy are the ones that only work with epoxy.

what about non, cut and double cut foam sheets, which do you use?

it all depends on what you are doing and what you want by using a core !! double cut gives better compression strength!! the cuts use lots more resin so if you are into lightness don't use it !
