I have got some, and use it on glossy necks if they ever feel too sticky. It's the main constituent of a lot of car waxes and is also edible, and used as a glossy coating on sweets/candy and some fruits such as lemons.

'Hard' here is relative term. It's a lot harder than say a beeswax finish, but soft compared to a nitro, poly, acrylic or Tru-Oil finish.
