There are some members of electronic forums that suggest coating automotive

Are they nuts? Grease between terminal elements?

It's fine, because the posts are soft lead, and so is the terminal lug, and
so they deform to fit one another squeezing all the grease out except in places
of poor contact anyway.

What grease--if any--is best, inside or outside the terminal connection?

Dielectric grease is good, but you can also purchase a strongly reducing
"battery protectant" material in a spray can which is grease-based and works
well.
