I foxed my RocketBox on top of my car with epoxy, there was a giant crack right down the middle, and I patched it up, worked amazingly. BUT! After it hardned there was no way i could "flex" it at all, it was literally a rock. Get what I'm saying? A board needs flex no matter what conditions. Epoxy will make a board very, very, very inflexible. If you still want to do this, I'm curious about maybe using a super soft SUPER soft board, and expoxying it to make it an all mtn??? maybe.
So you used the Vht spray epoxy paint I linked? I still have the cutout from the swallowtail. Might have to experiment with that.
