First day of needing my air conditioning found the system to be coming up short so instead of the usual $55 trip to my garage guy, Amazon delivered a can of R134a refrigerant AC Pro for $24. Works fine so far with enough left over to do another car.

My new past time since swearing off news is Netflix and Scotty Kilmer who I follow for entertainment and advice. He has a video on 5 of these products dealing with main seal leaks to lens protectors, to head gaskets.

Which begs the question “what products out there are good and which ones might make matters worse”. I’ve heard horror stories of radiator leak solutions doing extensive damage. Tire leak solutions gumming up the valves and rims, etc.

Wondering who of you has had good or bad experience with these types of products??
