behaves like oil

 when it gets on the track.  Very slick!

Really? I've been out of it since '91: till then there were no issues
with it...

 > As for cooling properties, I think glycol is lousy, so unless you really

 need the freeze protection, use some kind of corrosion inhibitor instead and
 let the water do the cooling.  Just my $.02 worth.

I helped fix a Super Vee motor once that froze in the garage and popped a
freeze plug out. No anti-freeze...

It was 19° F ( -1° C to those of you in OZ : ) ) 2 nights ago here in
Dallas. I want
my airplane to be as all-weather as possible. Also to be finished as
well... : )
