I've been polishing the playfield on my JP, taking it easy to try and not cause any problems. However, I noticed a spot over the edge of an insert where it appears that the paint and clear coat is delaminating from the plastic insert. I used a pin to get some super glue under the flap to try and secure it and keep it from further delaminating. However I now have a bump where this occurred. So I'm looking for tips/advice. Did I do the right thing? Can I keep this problem from getting worse? Leave it alone and hope for the best?
