I too thought it was conductive.
I bought a squeeze bottle of the stuff and use it on those pesky spade
connectors that rip the skin from your fingers when you try to remove them
20 years later.
For the record I had previously tried using some cool red Chevron 100
percent synthetic grease on the battery terminals on my Porsche. This turned
out to be a very bad idea, the stuff lost all moisture and turned to a kind
of red non conducting nail polish. I found out the hard way when it stopped
the voltage to my instuments in a very on/off fashion. It actually shorted
and ruined one of the boards in the instrument cluster.
why not just use moly grease?
