Best seal of all gaskets tested
I pressure test all my repairs especially cooling system before it leaves my shop, hylomar M seals better than any gasket. It cures to credit card thickness, perfect for most work. I like it more than hylomar AF with a gasket, has eliminated come backs. Be sure to follow label directions no wonder all the high dollar mfgs. Use this

Works very well
Hylomar is a gift from the gods. Doesn't leak and can be removed with a brush and brake cleaner.

Fuel proof seal
Extremely fuel resistant, goes on like a gel and firms up. Glue like, but parts can be separated, then reattached without needed more product. I used it to seal fuel sender gaskets and hardware to aluminum tanks on my Aircraft.

I have used hylomar for years, formerly under the Permatex brand, and it works very well. nonhardening sealant is very easy to work with and clean up when gaskets need to be replaced.
