Before anyone quotes resin sellers tech spec at me I know they all say it is no problem. But at the end of the day I have seen too many polyester repairs fall out of vinylester layups.

Kitten much appreciated, after talks with a few others, im gonna go epoxy. I have some stringer hollows where the foam sat into spray rails, I intend to fill this with epoxy mixed with high density filler 404, then over laminate. 45/45 cloth.
What filler should I use to bed balsa down, does it need to be soft or hard. Balsa is hard under compression so should I match it with more high density filler, or something easier to sand anfd fair?
