A coat or three of a good paste wax would be nice but as far as need too
goes and assuming the first of three rules of finishing is followed, "pick a
finish that provides at least the minimum protection commensurate with the
use the piece is going to be put too", I don't see why you would put
anything over it.
That's why Danish oil is called a finish and not pre finish, or finish
preparation, or finish sealer, etc.
