Nickel-based anti-seize. Copious amount on both sets of threads and mating surfaces.

About the spinner, I whack it real hard, then once more for the 'ell of it.

I usually leave the safety wire with a slight sag in it, i.e., not really snug. Then I check every couple of days, and if I find a wire that's taut, I whack the spinner hard again.
