Minwax (?), as with any other wax, can be applied over any cured finish.

My tin says nothing about a sealer, but wax isn't worth a lot as a finish,
anyway. It'll do for an "art" piece, but nothing useful.

Currently i have applied mini wax over Tung oil and have been happy with
the
finish. Can this wax be applied over a sand and sealer? ( the cans
instructions state that it must be applied over a sealer. What about a
shellac based product? )
