How much play is it going to get?

If it is going to be at home and played a few times a month, keep it clean, waxed, and keep new balls in it. It should not wear much at all.

If it is going to get a lot of play and not be maintained, pull it apart and clear it.

If you want it to be a show piece that you use as a conversation starter, clear it, mod it, fully pimp it out and never play it.

I'd put some 2 mil Mylar down exiting the fish scoop to prevent any "fish wear" from popping up. I'd also look into Mantis protectors for the fish scoop, as it doesn't look like any protector is in there. In full disclosure though, I'm pretty anal about the condition of my pins, LOL. I usually buy all protectors available, either Mantis if the playfield is in close to new condition, or Cliffy's if the playfield is more blown out. Sometimes a combination of the two, as I like Cliffy's ball trough kick-out protectors on all my pins, and I also like Cliffy's switch slot protectors where balls drop on the slots in the inlanes.

Putting Mylar in the shooter lane isn't a bad idea if you have a nice condition shooter lane, and if you don't have Mylar in the pop bumper area, I always do that. Seeing this is a Williams pin, I think you'll find factory Mylar in the pop bumper area.

Wax and then mylar any ball drops and bumper area (slings if you want to).

I would adjust your Start City Event scoop so that when the ball kicks out every time it doesn't get any air before landing on the playfield. That's how fish wear or the green area just below it gets worn or chipped down to the wood.
