a grease is a grease is a grease.
what sets a grease apart as suitable in aircraft is that it doesn't become solid when frozen.
personally I have not found aviation grease to be that special.
following a recommendation from an old aviator on my airfield I have been using water resistant boat bearing grease on my aircraft for over 10 years now.
I've never had a problem with it and since adopting it I haven't had a taper roller bearing develop any corrosion.
the water resistant marine grease has the advantage that is comes in smaller packages and there is less wasted grease.
if you want a molly disulphide dust. in australia a good item is PowerPlus graphite powder. it comes in a 35 gram plastic squeeze bottle.
I've used that when lubricating my vacuum pump carbon vanes after a washout for years now with no problems.
