Agreed.
Vaseline is better than dry or old lube.
Cheap and easy to get.
Easy to use.

If assembling for a season, maybe something better.
Keep in mind, very limited movement so lube quality is less of an issue..
Yes, some may say the "wings will fall off" if you use the wrong lube. In this case, not likely.

I can't agree with the "anything" specification. The main pins do not move, but the lift and drag pins clearly do work in flight, with considerable pressure on them. Any glider a few years old will show signs of wear, galling, or Brinelling on those pins. From this is seems to me that something with some extreme pressure ingredients is desirable.

I bet the wear is mostly due 1) sand and dust getting into lubricant, 2) rigging with force instead of correct technique. Light-coloured lubricant is better in this respect, it turns into black when dirty, telling you that interval between lubrication is too long.
