From what I could determine, a few of the characteristics for good
lubricants are stable consistency over a wide temperature range, not
out-gassing? (vapor releasing) and anti-bacterial to combat fungus.
FWIW, fungus will actually etch glass, much like squashed bugs on a
windshield do.


Dunno about anti-fungal, but vacuum grease meets the other two
criteria and I've used it on optical components where a very thick
grease seemed desirable. Permatex makes a clear synthetic grease that
has a lighter consistency than vacuum grease and is quite stable, but
I don't about its tendency to outgas. It's much less expensive than
vacuum grease.
