I have been working on my new addition, JM. The playfield is good, with one defect. At some point in the past, some dingaling drove one of the screws that holds the left flipper mounting plate up through the surface of the playfield. This left some cracking and a small bit of paint loss in a pretty high traffic area. The damage is slightly raised, but just barely and not so much that I think it would affect gameplay. I don't think the offending screw is there anymore. It has either been pulled back or replaced with the correct one.
I'm interested to know what the consensus is for repairing this or, more likely for me, just preventing it from becoming worse. I do have a mylar circle I could put over it, but I worry that someday when that mylar comes off, it will further pull off the compromised paint. Any other thoughts on ways to prevent this from wearing further? Thanks all - I appreciate your advice!
