Hi there..

I must admit I don't know much about high performance stuff on vehicles, but I do know about Methanol. I truck the stuff around all the time, its my job in the Albertan Oilfield, It must be handled with care, it gets into your blood line through the skin and your body can never eliminate it, and it damages the liver. Also it burns clear, like the "Shake and Bake" guy in that nascar comedy, you end up on fire and everybody around you is wondering why your running around like a headless chicken. As for brake and gas line antifreeze stuff its Methanol but they also add lubricants and conditioners to not dry up rubbers, it might help or might not for what you want to do with it. Any oilfield service company will have the stuff in stock, by the barrel its just about the same price as regular gas..
