First of all Im not hear to bash classic arcades. About 6 months ago i put on a overlay. I sanded playfield sealed it with wood sealer and let it set for 2 weeks and scuffed it up and cleaned before applying overlay.it went on great made the game look brand new beside the color of the 7 and 15 ball being off a little i was really happy. Today i had a switch acting up so i took glass off and decided to wipe it down. All my inserts are rough i guess it starting to lift. I didnt clear coat it because jeff said it didnt need it. I will buy another overlay from jeff. I just want to know if there is something i can do so this dosent happen the next time.
