most of the above, plus (off the top of my head, so most likely more besides):
modelling material for lost wax casting of metal
simple thread locker (rub it on a screw that keeps coming loose and it will stay done up)
sealing and burnishing the edge of leathr sheathes
sealing and polishing wooden furniture
holding small pieces in place whilst engraving them
closing a small pot containing jerky (it created an air tight seal)
as an electrical insulater to stop a torch from shorting out
rub it on a bow string to keep it from fraying/splitting in use
coating forged work with a waterprofing and shiny coating
making furniture polish
making canvas waterproofing
I'm sure I've used it for other stuff too
