"get a grip".....on what?
LOL, Just Kidding

I reiterate, I agree with you 100% on how a large variety of refrigerants can make it extremely hard on shops.

I am also a believer on a good repair and recharge with the original refrigerant.

I only disagree with calling Legal and EPA approved refrigerants snake oils.

WHY?
Because I (and you) quote information from their website as well as Federal regulations to prove our point. We have in our signatures that WE ARE 609 certified (EPA).
I find that calling snake oils those refrigerants that the EPA approves makes me (and you) certified by a "snake oil agency".

IMHO, it takes away credibility from our "609 certification".

Thanks again.
