How much is enough? Im using it on gaskets that go on the raisers and it goes on with a brush..The gaskets have rubber on them that go around the water ports but I want to use enough but not too much that it get in the water opening. Will just a thin coat do the job? Also..Does it go around the part of the gasket that goes around the exhaust outlet of the riser? I would think not because nothing goes on the gasket between the manifold and block and it seems like the same type of material on the gasket.
