Review: 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
