Re: Old Debate Revisited - Poly -v- Expoxy - which??
I've used epoxy for everything on this last project... mostly because I like the properties.. slow cure (I've been told that you can still get chemical bond up to 5 days) strength, ability to bond with just about everything and ease of use to name a few. It costs more and that is a problem if you are making fiberglass parts. I would use Vinylester if I were to build another engine bracket just because it is cheaper and wets out a little easier and thats the only reason. I'd keep it simple.... for repairs use good quality epoxy.. for making large parts go with polyester or vinylester.
