[RE-wrenches] ice accumulation

[Bill Loesch]

Hi Ron,

While you might put this into the same category as the RainX; I would
consider using some type of glycol mix perhaps delivered by a Dole style
(temperature sensing) valve. Glycol is what the transport aircraft community
uses before launching an aircraft into current ice conditions. The Dole
style valve only dispenses the gravity fed glycol when near freezing
conditions exist.
