Thermagasket for head gasket repair (auto)

[Carl]

Has anyone heard of or ever used a product called thermagasket?

http://www.rxauto.com/ It's made by Rx Auto It's proclaims to fix a failed head gasket. I have a '99 ford windstar with 128K miles with a bad head gasket. I tried the BARs product which did not work. The cost of the repair is not worth the value of the car. The thermagasket product is approx $100.00 plus S&H. They say you get a full refund if it does nor work, but I don't know how you prove that to a company in CA.

Any thoughts?

Thanks

Carl
