Ditto on the anti-sieze. We use it for installing spark plug into the cylinder heads of piston aircraft engines as well as the igniters in turbine engines. Without it you would never be able to get the plugs/igniters out without damaging the engines. I recommend it for all parts being screwed into places where heat will be an issue.
