I'm finishing an exterior door with spar urethane. The door is for, and calls for 3-5 coats with light sanding between coats. One side (the outside) of the door went fine. I have one coat on the second side, let it dry overnight and sanded it. As I was blowing off the dust, the coat started peeling off one of the inside panels, much like the peeling of a sun burn. It is not doing this any where else on the door. Any ideas or solutions?
