A bit of rust removal, painting, re-wiring and button replacement was done to restore my friend's Astro City "candy cab" arcade machine. We even upgraded the speakers to something nicer sounding.
The Marvel vs Capcom game board shown has the InfiniKey mod.
Make sure you use an anti-rust product, as scrubbing won't remove all rust.
