I think most of those suggestions are overkill Ralph. If you run a motor hard for hours in humid conditions, I might believe using those extra precautions but most of us never push our boat motors that hard in those condition. It you feel it is something you need to do, I would not put and more than two types of grease on your plugs. The di-electric grease on the tip of the plug where the boot goes on and a very small amount of anti-seize grease on just the threads of the plug. I agree with Kent though, I don't use that stuff and imo I don't think it is needed for most boat motors but again, it likely depends on how hard you run them.
