<VV> A/C For 69 Corvair

[jimster1]

Yup, it's good stuff.  It doesn't turn into a poisonous gas when exposed to
elevated temps like R134.  Its downside is it's cheap and DuPont can't
patent it and charge exorbitant prices for it.

Bob:  I don't think this is a problem.  The ES12a (hydrocarbon gas) has a
higher 
ignition temp than both R12 or R134a, and is non-toxic.  Also, it requires
lower 
pressure on the A/C components and less horsepower from the engine to run
the 
compressor.

As I said, I ran it without problems in my other car, and I like the idea
that 
it's non-corrosive when contacting moisture...Bill

Isn't Envorosafe propane based? 

And wouldn't that be highly dangerous to use around spark ignition engines?

And wouldn't it be unsafe to use in Corvairs?
