"Is there such a thing as a conducting antiseize?"
Absolutely. There are FDA-approved food
grade compounds which are usually teflon based, and those do not conduct. But most antiseize compounds are a mixture of nickel and copper dust in some type of oil
. The oil
may not conduct, but the dust content is so high that the paste itself will conduct. And note the instructions to use it sparingly, the stuff spreads like silver paint
on your fingers and your tools and everything it touches and you wind
up "decontaminating" for days if you've been too generous with it.<G>
