What's the best way to clean the metal frame pieces that surround the coin door? I'm guessing what I assume are pit marks are permanent? Do the pieces have a finish that will be hurt by soaking in a rust remover? What's the best I can hope for?

Put them in Evapo-Rust over night. In the morning, rinse the parts off with warm water and dry them. Now polish them up with either Brasso, chrome polish, or Simichrome metal polish and they will look great again.

Soaked them overnight and polished with metal polish by hand and then with a buffing wheel. Is there a way to get rid of pitting? Should I expect any better results?

Evapo-rust or any other de-scaler is the first step of a 3-step process for me.

2nd step is sanding/rubbing with scotch brite (green side) soaked in a powerful cleaner to remove excess rust OR glass-blasting when the rust is too deep

3rd step is metal polising in a bench grinder with canton flannel wheel, and buffing compound for non-ferrous metals.

this way I get perfectly new and polished metals

Update. First of all, I'm no expert. Based on responses and research, did the Evapo-rust, scotch brite, metal polish by hand, polish by drill attachment and finally tried using HF buffing wheel using the black compound. Here's the outcome. Not a whole lot better in my opinion. I've repainted/stenciled the cabinet so now the door frame sticks out like a dog. What's the best way to get rid of the pitting?

The pits in these are too deep to remove.
Marco sells a set foraround $50.

Wish I had seen them earlier. The Marcos site says they're for late EM and early SS Bally. Will they fit a Williams Space Mission?

Also, does anyone sell a Williams door skin like the Bally on Marcos?

Thanks

I thought those looked like Williams. Are they not stainless? How did stainless pit up like that?

You could "regrain" them with a coarse brown Scotchbright pad. Move the same area of the pad going the same direction to keep the grain in the right direction.

I've done this with badly scratched side rails (nails removed of course).

oooooops... Indeed the first photo you posted misled me. The pits from rust must be really really deep! You could regrain them as mentioned with a belt sander (not by hand or drill), but this would take time and it'll maybe make the metal more brittle (less fat).
To be honest, I would buy new.
Marco (in my experience) has excellent customer support. Mail them for details about the product

Rustolem (sp?) "Hammered" paint, is an $7 option with those, pitted in that condition vs. buying new.

+1 to hammered paint. It will hide the pitting.. well at least make it look better. That will take a lot of work to remove otherwise.. you'd have to coarse sand down to deepest pit depth, then sand up in grit and repolish. Vs paint that could actually make it look pretty cool and take 10 minutes

Marcos advises that the Bally Trim they carry won't work on a Williams (they look real similar to me) and said it's not looking good for any Williams to be reproduced. I guess I'll see how the door polishes and then decide whether to paint, polish or punt the old trim. Unless someone knows where else I could find a set?

You could check ebay, I've bought several coindoors complete with trim in the $30-50 range. Or keep an eye open for someone parting out a machine.
