Here"s this issue... somebody without a CLUE of how AC works will buy this stuff and figure "more is better".
ONE can of it probably doesn"t make much difference, but when you give BLEMS easy access to it and put it on SALE, they never know when to quit.
Likely, the system will keep leaking and the BLEMS will keep adding stopleak/dye to it "til the vehicle expires (for some other reason) and goes for scrap. ONE tiny application of dye should be quite enough!
If someone does try to repair it correctly before that happens, they are in for a messy job!
