There are few brackets here and there - e.g., the front cabinet bracket that the playfield rests upon - that were so blisterly rusted that I had to grind away whatever coating (e.g., Zinc) just to get the rust off; of course, after a few years they have rusted again.
So I'd like a solution that will stop this once and for all. Yes, painting is an option, but it always seems to look bad. I guess the gold standard would be for some shop to galvanize the parts, but that sounds expensive; perhaps there is a do-it-yourself way to galvanize? Or if not galvanization, some other coating? (I don't want to blue the parts as I'd like for them to stay silverish.)
After dipping a pair of these especially rusty parts in Evaporust, I'm going to sand down the surface to at least not be rough.
