I have a very small AC leak, that I can't locate. I lose about 12 Oz. over 12 months. I know that I should really fix it properly, but so far numerous attempt, and methods to find the source of the leak have failed. Neither UV die, nor a sniffer proved to be of any benefit.

So in the interim, I purchased a 14 Oz. can of R134, which also contains an AC leak sealer, as well as the appropriate ratio of oil. The sealer is claimed to seal most small AC leaks, except those around the AC compressor shaft.

Does anyone have any first hand experience toping their AC. system with this stuff?

Phil
