That's duplicolor at checker for that price. At least out here in Az it is. Kmart has it for about $90 a gallon /kit.
It's great stuff, but a word of caution, dont buy any that has been sitting on the shelf for a long time. The rubber
particules settle in the bottom and set like jello does.
I tried mixing it back up but all I could do was turn it into smaller chunks so it did not turn out as clean as the fisrt time I used it.
