Very new at this - doing my first restoration now (1978 Bally Black Jack) and it's about 80% done. For the coin door, I totally disassembled it, used Evapo-Rust on most parts, and tumbled the smaller bits in batches.

A previous owner hacked up an Atari button to add credits - drilled a hole right thru the skin and backing plate! I'm doing this on the cheap so I opted to keep the button and make it functional instead of spending $80 for a new replacement door skin.

It may not look like-new and it doesn't come close to some of the fantastic jobs I've seen on this thread, but it's now clean and functional!

That came out great, @phillyfan64!

Wow...that's gorgeous.

Finished my Black Knight coin door this weekend and this pretty much completes the restoration. Time to play!

1976 Night Rider EM - some Before and After shots. I keep forgetting to order a replacement flap for the coin door. Almost done with this restoration project!

I'm on the tail end of a Williams Flash restoration. Pretty pleased with how the coin door came out....I would like to have sent out all the parts to get re-plated but I'm already way, way over budget on this thing. It cleaned up great and I was able to get all the rust, gunk, and most of the oxidation off. Some stains and marks remain here and there that I just couldn't get out with the bench buffer, but overall I'm pleased.

Here are a few Before and Afters:

And installed in the machine....

I cheated, lol. I picked up a new repo Williams SS door skin from Bob's Pinball Stuff. Only part of the coin door refurb that isn't original.

Thanks! No paint. I used a few different grade wheels on a bench buffer to polish after the parts soaked in Evaporust for a couple of days. Did ultrasonic cleaning on most parts (that would fit in my cleaner) before and after the bench buffer treatment.
