Ah okay. Would probably be more trouble then it's worth then (not to mention much
smellier).
FWIW, back in the early 90's, I think, there was some experimentation with using
styrofoam and epoxy to make surfboards that were
lighter and stronger then the the conventional polyester resin/polyurethene foam
boards. They were able to make boards without the
wood stringer that normally runs the length of the center of the board to reduce the
weight. As far as I know, though, they are
back to using the conventional materials (albeit with the occasional CF
reinforcement)...I think the epoxy boards were probably too
expensive, and not worth the trouble.
