Intake manifold gasket installation help

I coat mine with CopperCoat on both sides. That seals them pretty good. I haven't had any particular leak problems in that area if it was sealed good to begin with. I usually hit the outside with some engine paint too, so, I can't imagine it would be a problem for the life of the engine. Most of the leaks I've run across while pulling an engine apart, was careless installation of the manifold or gaskets, or, missing sealer in the corners.
