Off Topic A/C Question

[Steve Sage <ssage@socal.rr.com>]

Does anyone out there on the lists, who works on their own A/C system in 
their cars, have any experience using Freeze 12 as a substitute for R12 
(freon)?

I need to add some freon to the Tiger's A/C and it's now $60-90 a pound 
as opposed to about $8 a pound for Freeze 12.  Plus, with freon, you 
have to have an A/C shop do it since you can't buy it over the counter 
anymore..

Thanks!
