Ah so it would be better to remove the old art then. I don't have the space in my apartment to lay it out and paint it. Not a good idea to paint indoors anyway. So I may need to transport it somewhere to work on temporarily when I get to that point.
As for the dust washers on the original control panel, since the joysticks are mounted under, is it layered between the metal plate and wood? Or is it between the wood and the joystick?
