Depends on the rest of your restoration and what you want to do.
New playfield, or have it clearcoated ? New plastic set ?
Or is everything in rather good original condition and do you want to keep it that way ?
Also do you want to sell the game when you're finished restoring, or is it a keeper for you ?
If it's a keeper, is it to play and enjoy the game, or more to look at how nice it looks and how well restored it is ?
