*pictures added* Your favorite methods to address surface rust on a steel frame

[warren128]

I have a 44 year old 531db frameset that I'm eager to get on the road. The original paint is remarkably well preserved with the exception of the usual spots where the paint got chipped for various reasons. As expected, those spots have surface rust. My plan is to get as much of the surface rust off as possible, and then use some car wax on the frame. I know that rust never rests, etc., but if that's all that I do, how long will it take before the rust becomes a structural "issue"? Is it months, years, a few more decades?

I'm not interested in restoration or in preserving the frame forever, I just want to get it on the road and enjoy it for a while before possibly passing it along to someone else. A look inside the bottom bracket, seat tube, and steerer shows almost no rust at all, so I believe the inside of the tubes are in very good condition.

Do you have any favorite methods and/or chemical solutions to address these minor surface rust concerns?

Thanks.
