[s-cars] Winterizing Windhshield Washer Fluid

[Kirby Smith]

The chemical used in the original GM Optikleen (c.a. the '60s) was 
methanol.  This is also used in the blue stuff I bought from the "Auto 
Palace" recently.  It may be used in all blue stuff for all I know.

Methanol at the concentrations used does not affect paint (at least 
acrylic lacquer, and I've seen no problem on my Pearl S6).  It disolves 
bug goo very well.  It would be unwise to ingest it, or keep your skin 
in contact with it for long.  Premixed methanol based windshield fluid 
would probably be a good source of water/alcohol injection liquid.
