Review on 🔧 Bar's Leaks Liquid Aluminum Radiator and Heater Core Stop Leak - Ultimate 6 Pack (1186-6PK): Save your Vehicle's Cooling System! by Brad Arthur

The radiator in my vintage road stick (supercharged 3.8L Pontiac V6; custom aluminum radiator) started to leak. Yesterday (10/10/18) I added about 3/4 bottle and drove (according to the instructions) 1/2 hour on the country road. When I got home, the base of the radiator was dry to the bone. Needless to say, I was thrilled because pulling out the radiator (36 Chevy) is no easy task. I've been a minder my whole life and yes I know all about the ins and outs of fixes in a bottle and yes I was hesitant to use Stop Leak. But just because it doesn't work in one situation doesn't mean it won't work in another. I keep my old car in near perfect condition, the coolant is always clean and the radiator is about 4 years old. I consider this post the first of "several" since "success" can only be ascertained after some time. UPDATE: I've changed my rating to 5 stars. This stuff worked exactly as advertised.
