Its good stuff, Ive had to use it before doing a head gasket on an old AMC V8, it seals the little imperfections in the metal so nothing leaks. Also good for high heat exhaust manifolds to make sure the gaskets seal. What did you intend on using it for?

I had to re-do one head on my vg30dett but didn't use the sealant just the raw head gasket. Hopefully somone else will chime in but I don't think you will have a problem using it or not using it. All it will do is fill in any imperfections in the surface
