Frame surface rust techniques?
 

I have this frame with a cool teal paint job. I don’t want to strip and repaint, rather just keep the patina but neutralize the rust in some paint-chipped areas and then seal it up with wax or something to prevent it from spreading. What are some good methods for this kind of thing?

There is some info here on cleaning up rust before touching up paint Small rust cleanup on paint

i followed the advice per the link supplied above the SECOND time around. I think it is good advice.

The first try I cleaned the spots and did an evaporust soak, then touched up. Thought it was just fine, but after a year or so rust spiders appeared under the paint.

The second time I THOROUGHLY sanded to bare metal (some light brass wheel work with a dremel) AND added the extra step of using the PHOSPHO product noted in the link above. A word of caution. The PHOSPHO dripped a bit around my tubes and it seemed to darken existing paint wherever it dripped. Next time I would use it more sparingly as is meant I had to respray larger areas.
