I'm surprised this is new (or maybe I'm missing what part of it is new). This is S.O.P for glassing surfboards (except for the initial sealing coat). I wouldn't have known to do it otherwise. Glad it worked out, I hope others give it a try. It makes it easy to keep the glass cloth in place, but if you're not careful the wrinkles can be a mess to get out, especially if the resin starts to go off to quickly.

> Mix 1/2 to 2/3 of the epoxy you expect to use (cloth weight in

> Spread the epoxy on the hull using either a roller or a squeege.
> Make it a bit thick on the high spots (keel on the outside, sides

> Unroll and drop the cloth on the hull (Tape the hull edges when

> Roll or squeege the epoxy up through the cloth. Pull on the edges/ends
