Outstanding product
Great product. Shipping issue with leaking bottle, a cardboard mess; seems like a simple plastic bag would be helpful.

AC, refrigerant leaks
I had my new mini-split system vacuumed down, 3-stage pressure leak test and they apparently didn't follow the makers instructions which clearly note the high pressure test is necessary, yes it is This system worked perfectly for a few months then the cooling performance stated to diminish. After a year catting the AC service company and the makers tech support I decided to complete the high pressure test myself After 2 hours into the 3rd and finally 550 psi test, the ac psi gauge didn't move. However using this wonderful spray I detected a small slow leak and a micro leak. Now I'll inform the AC company and the maker. The trouble-shooting with the makers tech support failed to suggest to check the systems refrigerant psi simply because there wasn't an error code. A waisted year with no cooling or heating. This is a great product and it does cling to the copper lines extremely well over a period of time M

Best bubble I've used
This is the good stuff. I use it on HVAC, car tires, hoses, etc. It stays put and makes finding leaks easy. The bottle could be better designed, it is very slow, but it holds up.
