Removed some interior parts and found some minor rust/corrosion (see photo). While I've got things disassembled figured I'd scrape off the rust and repaint so the rust doesn't get any worse. Any recommendations for this kinda paint? I know nobody will see it, but I'll know it's there and might as well find something original-ish looking and durable so it doesn't need to be done again. Or maybe there's some standard to use for these and other hidden pieces of interior parts?
