I've noticed on a lot of the later WPC95 games the inserts get ghosting on them/a milky colour around the edges. What causes this? Is it anything to do with heat from the bulbs? Ie. LEDs would prevent more damage
Its basically clearcoat not adhering to the insert plastic. Can be caused by contaminants on the insert. Apparently quite a lot of late 90s Williams games came out of the factory with some milky insert issues. Heat may possibly make it worse. I know if you see an insert where a flasher has locked on under it and heat damaged it, it also goes milky.
