Hey Deacon
here something to try for rust on chrome. Very fine steel wool ( I think 00)that's double ought with Dupont chrome polish. Try it as they say on small area first. Comet cleaner and Bonamie or how ever you spell it, works with the wool too.
Save those old frames at least cut the straight tubing out of them cause you can make all sorts of goodies out of them.ie trailer top bars(wink wink) and other things.
