Ayoub I. Kaileh: This stopped the radiator from leaking on my 2001 Toyota Camry. Which in turn saved me $300-$400 to completely change the radiator. If you have a minor to moderate leak, I recommend you give this product a try. Thank you Bar's Leak!

olmscheid: I used this for sealing my leaky head gaskets. This is not the product Bars sells for that purpose. However, it still had a significant effect on slowing the leakage. I should have purchased head gasket sealer but I accidentally ordered the wrong product. OK results in spite of my error.

James Oscar Lawless: Sealed up a water to oil link in our moms older Taurus. Follow the directions and the seal is permanent. A moron could use it.

Pedram: Did what it said and stopped a block leak in a 2007 Mazda 3. I only needed to use half the container, so I still have some left for another leak down the line. Not much else to say.
