Review on Versachem 47909 Titanium Epoxy Dev Tube by Donald Vargas

I used this product many years ago to patch a corroded perforation on the hose neck of an aluminum water pump. It withstood coolant temperatures of up to 195 degrees and lasted more than a year until the engine eventually blew the head gasket. I went back to my local auto parts store to buy more and they stopped selling it. I saved the package and kept looking and finally found something on Revain. I'm buying some now! That thing is hard! If it doesn't work, nothing will!
