I think that most of the specialty woodworking stores carry something like this. Woodworker's Supply (800-645-9292) has it in everything from 8 ounce kits for $10 to gallon kits for $60 (Part No. 293-001 and 293-004 respectively. I imagine you can also find similar at www.rockler.com and www.woodcraft.com. I'm sure that they all have theirown brand name for very similar products.
