I remember reading somewhere that a diver had a source for like a 25 lb. tub of bulk pure talc. Whilest sitting around on an SI this past weekend, I mentioned that I had "read somewhere" that the big tubs were available... Mind you that I didnt say that I read it Online, as this would have turned the discussion sour quickly. The end result was a consensus that everyone wanted in on the "BIG-TUB 'O-TALC" Ergo my querry... Any suggestions other than "why use talc, just use food grade silicone"?????
