White lithium grease, oh my Keith, nooooo!  ;-)  ;-)

Grease is a dirt and grit magnet -- it would eventually
capture grit between the contacts in a roller inductor
or in the mechanism of a roller or air variable and
destroy them.

I do love white lithium for rotators, sliding doors, and
other such large-contact applications but would be terrified
to use it in small contact apps.

IMHO, YMMV ...
