From Bernard in Georgia: "I'm very excited about your product called K&W Permanent Head Gasket & Block Repair for it has made me a very happy man. My 2004 Chevy Impala was diagnosed as having a head gasket leak and I was given a very very expensive estimate to repair it. It was money that I did not have especially after I just moved into a new home the last thing I needed was an overly expensive auto repair. First I tried Steel Seal which was supposed to seal my Head Gasket but it failed. Then a local mechanic told me about your product and said that it would work and guaranteed that it would so I rushed to Auto Zone to purchase your product and let me tell you, it's like I have a new car. It's driving smooth, no overheating and no idle problems. I'm just so happy that my problem was solved."
