I love Hylomar!!

Reading about all these leaking oil pans....the wonder sealant Hylomar....makes me happy that I have used simple, cheap, reliable silicon [ on it's own ] for decades....& get no leaks.

Yup. That's its intended purpose. To BE the gasket. That's why it's called "Form a Gasket". lol It works good.....just takes a lot to do it that way. But it sure as heck will never leak if you do it right.
