Has anyone ever heard of IceClear HD coolant? It's glycerin based so it should be allowed out at HPR (and probably other tracks that ban glycol-based coolants). http://www.orisonmarketing.com/IceclearHD.html

Their site specifically states automotive use but I'm hoping there is someone more educated about coolant out there... It seems like it should be compatible with bikes as well but I'm still nervous to buy/try.

If anyone wants to try it with me I can only find it in a 4 gallon order for $84... and my bike only needs 1 gallon (2 if I am being OCD about flushing out the old stuff)...
