Hi John- You can get polyclar by mail order from Alternative Beverage, (1-800- 365-BREW) 114-O Freeland Lane, Charlotte, NC 28217. I think its a resin- and prizes range from $2.35/ounce to $21.45/pound in my old catalog. The people who answer the phone there are very nice, so if you need a lot more, or less, they can probably help. Bon chance Mer
