I just completed a cedar chest- box is black walnut- top is combination spalted maple, puple heart, black walnut and wenge.  I have begun to finish it with tung oil and was planning on finishing it with wax after I’m done with a few coats.  I’ve heard that you can combine polyurethane with oil.  Is this the case?  If so is this a more durable finish?  I might want a little more durability especially for the top…I plan on passing the chest on for generations!  Any opinions on finishes.

Thanks

I can provide more info if needed.
