Good morning, all...

When connecting a copper ground wire to a copper-plated ground rod, is
there a compound of some kind that should be used to inhibit corrosion?

I have asked the man behind the counter at the local electrical supply
store (where I got the ground rods) and he says it's not necessary, but I
have seen references to it here and there on the net including in this NG.

I thought about maybe using some of that Butternut conductive grease that
we use on our antennas.

Thanks...
