While researching dielectric grease I found this interesting article:

I personally use dielectric grease on battery posts, solenoid/contactor posts, starter motor and alternator posts, grounds, and automotive spark plug terminals and coil pack connectors. I do not use it on aviation spark plugs.

I use Permatex 81343 anti-seize on all spark plug threads and on frequently removed screws (cowling etc) to prevent galling.
