    Leak Stop
  

*by C***Y on Reviewed in the United States on July 14, 2012*

This product was a good investment. The results were good and today the air conditioner is still working.  It saved me from a very costly bill for my car.

    Did not work at all!
  

*by T***N on Reviewed in the United States on March 9, 2018*

Had a tiny leak between the plastic frame and the aluminum radiator, it was just leaking a little, like a shot glass on 20 miles. That stuff didn’t do it’s job at all!
