If you are spraying a clear (?) I would change a couple things you did. I use a little wad of painter's tape in the bulb sockets so they can be below the surface. I would also remove the flipper bushings and the anti-bounce back wires so you can really sand the whole thing. Most importantly, it will allow the finish to be applied more uniformly. Great game, you will love the way it plays if you have a smooth surface with the inserts leveled! Makes me miss mine......
