how much resin to get???

So with my last batch of boards, I went aggro and picked up the RR 7.5 Gallon set. It took me through a 12’6 SUP, 2 14’ paddleboards, a 6’0 stubby, a 9’0 log and I still have about a half gallon of resin and a third of hardner (dont ask)

Next up is 3 14’ x 28 x 5 EPS SUP paddleboards (for the racing, ohh how I love the racing) Its looking like I will be glassing with 6 oz under 7.5 oz volan onto a stringerless 1.5-2 # blank (but I may throw in some kind of composite stringer, Carbon stringer or kevlar stringer… who knows). Will most likely put a strip or 2 of something tough down the rails to protect from the paddle smacking, but I really just want these to be LIGHT!!!

If I have the space, I may try to floor glass, but I have gotten pretty good at glassing (low and behold). I throw minimal amounts on the floor, but have yet to be able to figure out consumption.

Please help…

I need to know about how much resin I should be mixing up per side with these weaves, which will tell me about how much to order…

George, feel free to chime in anytime…
