Bests & Worsts Reviews from Amazon

Worked perfect for me. I had such a small leak, I couldn't see it. I was real hesitant about using this or any other product like this because of various reviews. After doing some research and asking a mechanic at work, I decided to byte the bullet and give it a shot rather than paying $$$ just to have it looked at. Thank GOD, I used half the bottle and within a day, my leak stopped, Definitely recommend this product for minor leaks. Also, after I knew the leak was gone, I flushed my radiator and refilled with coolant and distilled water. 2 months later, still no leak :). Hopefully it stays that way.
