A tube of Nikon grease lasts me almost a year. I prep at least
one camera and two strobes a week. The o-ring should be just
shiney, with no visible thickness to the grease.

You should take a course in o-ring maintenance. Up here,
Backscatter runs them now and then.

And use Ike grease on Ike rings, Nikon grease on Nikon rings, etc.
Some greases will attack some rings, in particular, silicone grease
will attack the orange silicone o-rings on the Nikonos RS. BTW,
Nikon grease is NOT silicone, it's mineral. I've got the MSDS for
it somewhere. It does come in a larger container -- 55 gallon
drum from the actual mfg. ;-)
