Don't forget that grease today, at least the high tech stuff, is way better and more stable than what was used in the past. Some of the synthetics will probably look and feel exactly the same in 20 years as they do today, assuming they don't pick up a bunch of dust and lint. Many of the old formulations eventually turned into something closer to epoxy than a lubricant.
Interesting about electrically conductive grease and static- good use for it.
