Quoted from TheBeefSupreme:I am so glad to be wrong! Ha I saw your message and pulled off the glass, that’s exactly what it was. New pinball owner here so I still have a lot to learn. Thanks for your help!
Welcome. I’ve done that before too. Wax gets stuck to things and plays tricks on your eyes. The playfield can also look damaged and it’s sometimes just ball trails and dirt. Glad it was nothing! Tons of helpful pinball experts here, so always feel free to ask for help. I didn’t know how to remove the glass or change a bulb in 2016. I learned by trying things, asking for help and watching help videos. Tonight I’ll finish my first RadCals cabinet restoration by suspending the playfield from the ceiling and lowering the cabinet, so I can remove the pivot-hinge bolts in the cab. I saw that technique posted on Pinside with a Safe Cracker machine. Clever!
