I'm going nuts over the proper use of dielectric or thermal paste. I have a tube of thermal heat sink paste, the label says it is dielectric, thermal heat transfer paste; most commonly used to get good heat transfer between a microchip and a heat sink. Now I have heard several people, on this forum, say this stuff is also good to use on wiring terminals and contacts to get a good electrical bond and prevent corrosion at the joint. But when I read the definition of a "dielectric" it says that means it is an insulator. Won't this stuff actually prevent electrical contact and be very bad to put on a ground terminal, etc.

Some of you professional "Sparkys" out there please help me with this.
