Absolute best stuff for R12-based old timers as well as R134a
I was going nuts trying to find ANY R12 for a '77 Silver Shadow 2. My mechanic (John Palma!) suggested ths stuff. I added a can without the gauges because I knew the system was empty. The comperssor kicked in and I finshed the fill-up with the gauges. It's been six months now and the sytem has performed very well. I just can't imgine the amount of work i'd need to do to convert the beast over to R1134a. I'm too old for that nonsense. Very highly recommended!Yeah, I know, I shoulda' evacuated the system and changed the dryer. Maybe next time.The previous owner said the AC was broken and he didn't want to pay the $2,000 his guy wanted to "fix" it. It took me forever to find the correct R12-to-R134 fittings. Picky, picky, picky. Total cost to me was $75.

This stuff works amazing! Haven't had one complaint!
I fill and repair AC units in the spring and summer, this stuff works great. I haven't had one AC that it didn't work in. I used it once on an AC unit that would leak down from a full charge to empty in about 4 days(filled by another AC guy without checking the system first), it sealed it and hasn't lost any pressure since using it. I would recommend it to everyone.

I own tons of HVAC units in my rental properties
This stuff works. NOT on a giant leak that your freon goes out in a day or two but the more typical slow leak. Priced right works well.
