I have bought my first pinball (1976 Williams Blue Chip) which I plan to just get running and play, not to do full tear down and restore. The metal back door to the head has surface oxidation, few specks of rust but is solid. Would I anger the pinball gods if I gave it a coat of paint or sealer to prevent further corrosion? Thanks!
