Refrigerant and rebuilding AC (In defense of Durocool)

[Bernard Littau]

I was looking into the Duracool product, trying to find it locally, or at a
discount on the web.  I came across this EPA site:
http://www.epa.gov/ozone/snap/refrigerants/hc-12a.html

If I am reading this correctly, then Duracool is not legal for use in cars
as an R-12a replacement, and is not legal in cars at all in 18 states, which
my home state, Washington, is one of.

Freeze-12 appears to be legal.  What experiences have people had with
Freeze-12?
