If I am going to keep the pin, then I try to restore so it looks like it just came from the Gottlieb factory. This restoration will include a repaint. The fact is, I can not afford to restore a pin to all its glory, if i am going to eventually resell it. The market just will not bear the price for a fully restored pin thats has a repainted cab and/or expensive parts like a new backglass. If the pin is going to be in my collection for less then ever, than I will make it look presentable without touching up/repainting the cab or replacing expensive parts.
FYI - I do not perform the repaint myself. I contract it out. Or, of course, purchase a restored pin from Stashyboy or Boilerman where I do not have to do one anything except play it.
