I just finished my build and I have some leftover materials that I would be happy to give away:
1: About 15 pounds of Cell-O-Fill (the kit came with at least 3X more than necessary).
2: A few pounds of wood flour.
3: About two gallons of MAS resin.
4: About 3 quarts of fast hardener (about a year old, but no yellowing yet).
5: A zillion wood scraps, including a full sheet of 3/8" Okume that was used for packing material, and is sort of dirty and dinged up on one side.
The stuff is available to pick up in Princeton, NJ.
