Im in the same hunt. What I've found so far Great Lakes Drag raceway has it advertised for $48.00 per 5 gallon pail - which is too expensive. Other posts are reporting it should be $2 - $3 per gallon.
Dan Owings [email protected] has it in 55 gallon drums in Rockford, I don't know his price. Im sure there are chemical suppliers in Metro Chicago Area that have this stuff. I will report any sources found.
