Aloha from NH, is there a rule of thumb for for figuring out how much resin to mix with respect to length, (ex. 1/2 gal per 3’) I am bout to glass a 10’6" and want to get it right without wasting the liquid gold… Any help, advise or insight would be greatly appreciated … also, a good cc. amount of hardener for a long slow “kick” rate would be nice too… Thanks Jake Sullivan
