Yes, those prices are right in line with our kits. In our kits, the CF is sandwiched between two layers of a biaxial fiberglass sock. Also, the CF material on those sites are not exactly the same. Ours is a unidirectional material. Its not a secret by any means, but you do have to buy several thousand dollars worth to get a decent price. :shock:
We include the epoxy in the kits. We can also put in (at no additional cost) a post cure epoxy - phase 2 resin from system three. A couple hours at 140 degrees is all you need. We do not list it with the kit because post-curing could be scary to builders just wanting a small spar, but for the larger one is makes a lot of sense.
