Hi Sward, Are you vacuum bagging these layups with a mold or is it all by hand? I made a kevlar/carbon seat once and can say that you really can't sand this stuff except at the edge where it is cut and trimmed with a trim piece. I don't have whitewater experience but have been in the surf with a sea kayak and have used the plastic helmets. Seems to me the cushioning and chin strap attachment is as important as the construction helmet. George gets excited when anybody tries something new so don't take his comments personally.

I've wondered about carbon as a shell material, when carbon fractures it has VERY sharp edges. Keeping the whole thing carbon/kevlar might be safer should things break inwards.

As far as epoxy goes I don't think the brand will matter as much as the method of construction. post pictures if you can.
