Highside 32032 Hvac/R Instant Patch (JAYBRAKE 32032)

Tried this three times on a High side car A/C line, held vacuum for 30 min each time, but blew out every time in a day or two. The third time I removed the tube from the car and was very careful to clean it properly and orientate it so the leak was on top. put all back together and pulled vacuum for 30 Min again, held fine. Put in the refrigerant and it held fine cycled the AC a few times still held. after about an hour, driving down the road, the repair failed spraying refrigerant all over the engine bay and out of the hood like a coolant leak.It might work for you for a while but it didn't got me.Wasted a lot of money filling the system with refrigerant three times.
