DON'T use dielectric grease on the cap or rotor contact! The contact is a spring loaded carbon brush, it's self lubricating, and it sheds a small amount of carbon dust. That carbon dust plus the grease will turn the grease conductive, and the heat and centrifugal force will make it ooze all over the inside of the cap until you start arcing over.

In other words, it will ruin your cap and rotor eventually.
