Leak-detecting A/C recharge with leak fix ...
 

I've heard in the past that those leak-fixing products tend to gum up the A/C system ... anyone have any experience using these? There's a UV dye + leak fixer recharge I'd like to hit it with ...

I have never liked using those types of products, but I do believe they are fairly safe now. Early types had the potential to plug the orifice tube if there was a small amount of debris already there.

Ive had no luck with leak fixers fixing anything but they didnt do any harm I can tell though. The dye is a good idea so you can spot the leaks.
