I just stripped an old china cabinet, used a water based stain, and finished with an oil based polyurethane. This will piece will hold stacks of plates, wine glasses, etc. I am concerned that the pressure from the stack of plates will cause the bottom plate to stick, such that I will need to pry it off, and the plate will take some of the poly/dye with it. I have had this happen on another piece before, with poly over paint. Should I apply a liberal coat of wax to the shelves? Is there something else I can do to prevent this? This is our good wedding china I am talking about. If I mess this up, I am a dead man.
