You can buy at advance or autozone.

I used it the 1st time about 3 years ago in FL, where we need AC, when I had a slow leak. you can have anyone who can read do this but they must read first. "Immediately" after you run this sealant in you MUST run freon in right behind it or it will clog your charge port. I ran about 3 years on a 96 850 after I did this and it worked.

Then at about 205K I finally had to replace the compressor, and dryer, evac the system and recharge. And I had a slow leak, where?? no signs so I go get some super seal run it in and recharge, that was about 6 month ago. My AC is the coldest AC you could ever imagine, I mean freezer.

btw, If you have no pressure in your system you will have to have it evacuated (connect a vacuum pump to suck out all of the air and moisture ) and charged enough to get the low pressure cutout tom close and the clutch to pull in, then add the super seal then add enough freon to charge properly.
