I kinda wonder about cost/ benifits? I use the premix, usualy just under $1/gal. How much does the canned stuff cost, and how much deicer does it make? A long time ago a pump jocky filled my washer bottle with Antifreze, what a streakey mess.
The regular old premix doesn't freeze, but it doesn't exactly melt the ice on the windsheild too well either. Got to wonder what they use for Aircraft, they seem to be pretty generous when they spray down a plane. The big boys are always looking at the bottom line, so's I'd expect a certain degree of efficiency. Sorry I wish I could have been more help.
