I just purchased this blem playfield for my Pinbot from a fellow Pinsider. It is a CPR and looks pretty darn good except for the Sun insert. It is actually loose. I can access it from the backside. What glue should I use? After I lock it in place I was going to do a little hand touch up to make it look presentable. Then she is getting installed. I was thinking about installing a playfield protector on this one. Anybody have any advice for me in regards to saving the playfield? I want to do this one on the cheap since it is a blem to start with. Thanks in advance.
