The metal door frame on my 1969 Nishijin single shot is... well, shot. I'd hoped that I could remove the surface rust, polish, and be in pretty good shape. But the chrome (or is it nickel?) plating is flaking off in big chunks.

I'm looking for some affordable ways to address this. I found this thread on re-chroming that mentions a few options including a shiny silver powder coat. But most of the links in that thread are broken.

So I thought it might be worth starting a new thread. I gather a lot of people don't bother and just get a good door off a donor machine. Pachinkos are super common around me, so I don't think that's a good option.

Suggestions? What have you done that worked?
