Reddit reviews Red Angel A/C Stop Leak & Conditioner

Holy smokes I would have a very hard time trusting even the best mechanic in the world to put that all back together and not miss something electrical and potentially have to do it more than once, or screw it up entirely.

This type of thing might give you a 1 in 100 chance if it's a really small leak in the core or a seal somewhere, but then you have to put more refrigerant in it which might just leak right out again - and then you are just burning money and helping melt more polar ice.

I'd probably save the money there, forget it entirely and roll the windows down, and live with it. A beaded seat cover helps with air flow behind you. Carry a spare t shirt with you and a wash towel for when you get to work or whatever?
