Great alternative to expensive repairs (for some)
This actually worked for my 2016 Tacoma. The system could not hold a charge for more than half a day before it all leaked out and blew warm air. Now, my system is sealed and holds a charge. This has causes the old rubber seals to swell, like high mileage motor oil, closing off any leaks. My 2016 uses r1234yf refrigerant.

Simply great leak repair. It works.
Been using it for 20 years and this is simply the best I have ever seen or heard of. Why? I sealed a home A/C unit that lasted another ten years before replacement. There were several holes in the coil. 2 Cans later, everything was working and well.

AC leak fix
After charging the AC, a few weeks later it started to blow a little warm again. After charging with Red Tec, so far it's holding the cold. Hopefully, this hold 🙏

good price , fast shipping ,but
all seems well enough , but have not used it yet . Upgraded to a better gage tool and quick check indicates I likely have a condenser / clutch issue . Reads 0% high pressure . Back burner for now .
