Red Angel AC Stop Leak

I'm trying to avoid a $3000 + AC repair. Has anyone had any experience with Red Angel? It's supposed to work differently than other stop leak products and not clog AC systems or repair shop equipment. Thanks

I rolled the dice today trying to avoid a $2000+ AC repair job to replace my evaporator that has a small leak.

I did this after talking to the Red Angel 'stop leak' technical support folks. They assured me that Red Angel, unlike other stop leak products, is activated by contact with air and not moisture. Because of this, the Red Angel people claim that its stop leak product will not clog car AC systems or AC shop equipment. In theory it only does it thing where refrigerant is actually leaking into the air.

To get the Red Angel job done, I visited a local AC repair shop. They began the process by evacuating the system. Next, they injected a 2 oz bottle of Red Angle Stop Leak. They followed this by recharging the system with oil and 134a. After running the car for 10+ minutes, the shop used a sniffer to see if it could detect leaking refrigerant. It may have stopped the leak or not. On its most sensitive setting, the machine sounded a beep. It could be leaking refrigerant from my car or another. My car was downwind from a number of other cars having their AC systems worked on. Only time will tell if Red Angel works as promised.

So far so good. I'm not convinced yet that Red Angel Stop Leak solved the problem. In the past, it took about 4 to 6 weeks for the system to lose enough 134a to blow warm air. If it's icy cold at the end of August, RASL will have done the job.
