I use Vactan rust converter. It turns it a black almost lacquered finish.
My usual process with a frame I’m just trying to maintain rather than refurbish is to clean around the bare metal area then dab on the vactan really sparingly with a cotton bud or small brush. It cure after an hour or so depending on temperature. It can be rubbed down and painted over if needed.
I don’t know anything about the science! You can buy it in small amounts on eBay. Link to more info here https://www.performance-chemicals.net/vactan
