That is basically called Penetrox. It is used when bonding disimiliar metals to prevent galvonic corrosion. Used in electrical panels where aluminum wiring is joined to another metal, copper etc.

Dielectric grease, according to Tom Rauch, who is both a car guy and an electrical engineer

dielectric grease vs conductive grease

WD 40 if it isn't in an area where it would get washed off.

That terminal is exposed to the elements practically under the vehicle, right?

If so, Id look for a hardening or semi-hardeining waxy protectant after putting a thin layer of dielectric or a metal-bearing anti-seize on the threaded terminal itself.

CRC, LPS, Amsoil, Eastwood, plenty of others sell them.

There used to be an aerosol grease called "No Crode", meant for battery and starter terminals. Don't know if it's still available.

You could use rubber cement too. Like the tire repair glue.

After working with -48 DC in my phone career, I learned a few things. Grease applied to connections is displaced where it contacts. We used stuff that was mostly Vaseline. I use whatever is in the grease gun. I use it on brake line couplings too.
