To "anti-seize" or not, is the question.

Any metal based (silver aluminum, copper, or black nickel) will work just fine. On any high temperature application, like spark plugs. we always used nickel due to its excellent high temp properties.

Thanks JFP! I bought a can of black nickel anti seize about 20 years ago and still has a lot of paste inside..

On applications like spark plugs or exhaust manifolds, it cannot be beaten. And I have no idea how old mine are, we buy stuff like anti seize or PTFE thread sealer in the largest containers they make as just about everyone in the shop is constantly reaching for them; they are consumables like shop towels or toilet paper, and like them never go "out of date".
