Hard to think there is any techincal requirement for special grease with glider main and lift pins. The enviroment is not that extreme. Just put some clean vaseline on pins and clean old dirty vaseline off every time you rig. This has been done succesfully for close to 100 years now. Some pin wear is pretty normal during 3000 hrs no matter what grease you use.

Absolutely. I have been using plain automotive grease for the last 20+ years on my gliders and can't imagine why I should give it any more thought.
