My A/C guy has plenty of it, gets it from Mexico I assume.

It's great to have for older systems, works great of course but r134a works well too. I've owned or ridden in plenty of old cars with 134 conversions that blow cold.

I like to keep them R12 if that's what they came with. My dad's 1980 450SL blows ice cold with R12 that's been in it for ages, (maybe original?), including years of sitting. There is a lot of misinformation and lack of knowledge about auto A/C.
