Worked for me!
Used it on 97 Grand Caravan with rear AC. Worked great! Before refridgerant would leak out after about one day. Still working a month later. I am selling this vehicle. If I were keeping it I would recommend have a shop pull a vacuum on your system. That would also check how big of a leak you have. They should be able to do that for around $50. That way you won't be over pressurizing your system= should last longer and less likely to start another leak. Do this.. go home.. then follow directions. Shops don't like getting this super seal in their expensive equipment. But for a cheap fix compared to $700. repair. It's hard to beat. Yes, for a really big leak it won't work just as it says on the directions. You can now buy vacuum pumps I believe for less than $150. Would be a good investment if you can afford it.
Bottom Line Yes, I would recommend to a friend

Maybe I just had a bigger leak than this could handle, but it did not work at all for me.

Figured it was worth a shot in my 02 Ford Focus. My system had some pressure but after adding refrigerant last year it only worked for a short time. This year I added a can of this sealer and after two weeks it is still cooling nicely. Would NOT recommend using more than one can of this sealer as from what I've read it can clog up the system and require professional flushing.
