[TR] Best Anti-Rust Coolant

I'm not a chemist, but adding antifreeze does raise the boiling point.  For
commonly used concentrations, it's only by 10 or 15 degrees F, but it does
raise it some.  There is a chart at
http://en.wikipedia.org/wiki/Ethylene_glycol

Whether that is enough to compensate for its otherwise poor effect on
cooling, I don't know.  In my limited tests though, it would seem not.
