I just now saw this post, and I have to say I'm curious about this stuff, at least from an environmental point of view. As far as track use goes, the question is, if you spill it on the asphalt, will it evaporate as quickly, and completely, as water? The literature says it's more viscous (has a higher viscosity) than glycol, that doesn't sound so good. How slippery would a mixture of this stuff be?
