I recently built a jewelry armoire for my daughter that has a polyurethane finish on top of a stain. I now would like to add a panel to each side. They also has a polyurethane finish on them. Having these panels is a last minute "option" that developed after totally completing the armoire. So, now I'm undecided as to the best way to attach the "poly" panels to the armoire: double sided tape, CA or glue. If glue, what would be the best glue to attach two polyurethane finished surfaces. I have doubts about using the Titebond glues as they soak into the wood to get their adhesion as that wouldn't happen with the polyurethane finish.
Whatever the choice I'd like to see a tight fit if possible - I don't want the panel to stand off the armoire, i.e. no gap.
Any suggestions?
