I’m thinking of shaping a board with single 4oz epoxy glass, what do you reckon that is equivelant to in polyester resin in terms of strength. Eg. Is 4oz epoxy on its own as strong as 6oz polyester or double 4oz polyester?
4oz epoxy is only slightly stronger than 4oz poly… and not by an significant amount, IMO. If you want a stronger product, you need to lighten the core and glass heavier. That’s how you end up with a significantly stronger product that’s about the same weight or slightly lighter.
what do you guys reckon the lightest epoxy glass job would be that is going to be durable?
if my memory serves me well, the minimum on the epoxy boards by greg loehr, is 15oz deck, 10oz bottom
so now make the [weight] deductions yourselves
good luck
