In terms of finding a chemical used to "convert" rust, I have found Naval Jelly to be quite effective. Found at local NAPA auto parts stores and various others, it is a jelly that you just brush onto bare metel and then wash off. I have used it on the body of my spitfire with great results so far. Just head the warnings about not inhaling the fumes. I speak from experience, you don't want to be that sick.
