Hey enough already. I to have give up on Zap finishing resin. It is too thick and if you thin it down with either rubbing alcohol or denatured alcohol it becomes like rubber. It will not harden if duluted. I to wanted a new method and am now glassing my new Giant Corsair with the water based polyurathane. Even Nelson aircraft has recomended this method using thier water bassed clear. You can buy a quart at Wally World (Walmart) for a few bucks and have enough to do almost two large birds. And as said before it dries in minutes. I covered my entire fuse in just a couple of hours and that is with two coats. Only caution is to go sparingly on the first coat so you do not warp the wood surface. Also if you are glassing directly over foam go back to the epoxy method.
Well thats my 2 cents worth.
As you can see thier are many ways to skin a cat and they are all good methods
