George,
hard wax oil has a couple of problems, that once understood are easily overcome. It's very thick, about the same as golden syrup and about as sticky.
1. Applying it needs a small brush, I've never successfully managed to use it with a cloth.
2. It cannot be placed onto a surface wet. I normally hang items to dry or if used on the outside of a bowl, then have to place the bowl upside-down onto a stand onto the inner surface.
I particularly like it for scorched forms and as I've brought a couple to the club in the past you'll of seen them, even if not knowing the finish.
