I used this product on a small crack on my XT600 motorcycle, after 3 years, absolutely no oil leaks

So far so good - handle was loose on frying pan

Was using on an Engine Block because of heat and because it states on the packaging that I could use it as such. Applied to the vertical side and it literally ran down the side and dripped off. I degreased the place where I was applying and scuffed it up with a dremel. Additionally, the thin layer that stayed was brittle after curing. States it is a paste rather than epoxy but was very runny. Most of the 3 oz ended up on my garage floor. Called the company and they said not to use it on the engine block and referred them to their packaging. Oh well.

used it , let it cure and wrapped it with " Exhaust weld wrap " and presto it is great
