Anyone ever use conductive grease?

I use a lot of dielectric grease, partly because I have two boats. Dielectric grease is non-conductive and does a bang up job of preventing corrosion, which prevents high resistance connections, which prevents heat, etc. I squeeze it into crimp connectors, use it on terminals, etc. Used in spots where corrosion has caused a failure it does a great job of preventing a repeat performance.

There is also conductive grease -- available in silver or iron. It's used in big switches and stuff like that, where you have a moving connection that needs to efficiently conduct current. It's also used by electricians dealing with large cables and clamp-on connectors. It allows for a better connection with less clamping force.

Now, I've been thinking. Might this not be just the trick in certain places for our aging electrical systems, use sparingly and with care? What would a dab of it do -- for example -- on the tip of a tail light bulb that likes to flicker when going over a bump? Or on the strands of copper in a battery cable before clamping on the wring terminal?

The conductive grease that I'm familiar with is copper based, trade name Copr-Shield, good stuff, but expensive, use it all the time.
