Enviro-Safe ES-12a or CoolTop Info?

[agm2003]

Does anyone have any input about:
Envirosafe ES-12a
or
Cooltop (Mix of R125/152a/134a)

in a 134a converted system?

Thanks

Did the es12a into a 12r system Friday. It's worked ok in heavy traffic the last two days with temps in the 90's, but it hasn't been long enough to tell if it will eat it's way out and destroy the system/car/or me yet.
I figure next spring will be a long enough test period to see if it works ad advertised,
(I really didn't risk much as the dang thing wasn't putting out much 'cool' anyway, and Fl summer is here!)


BTW the only difference between the 134 and 12r kits is the size of the fittings.

The es12a is claimed to mix harmlessly with 134 systems (or 12r)

BUT... "it is against Federal law to do so"!!!!!

Thanks for the input. Has anyone had any long-term experience with either Envirosafe ES-12a or Cooltop (Mix of R125/152a/134a) ?

BTW--What exactly is in ES-12a? Is it a mixture? If so, is fractionalization an issue here as well?

Review on e-bay claims it's Propane. I dunno but it's still colder than 134a.

(2 weeks of constant use and it's still cold! and dry!)
