bare metal frame or paint it?
 

so i recently stripped the paint off of my old KHS Gran Sport road bike. i was originally going to rattle can paint it but my first attempt at painting it failed. i re-stripped the paint but i am realizing i really like the bare metal look and want to keep it. anyone know of any good techniques for keeping the bare metal but without it rusting up? i heard that clear coating it doesn't work because the clearcoat chips off in about a week. i heard one technique works is using a metal polish like Mother's Mag and Aluminum Polish and just apply it monthly. i also heard from a guy in a bike shop that heating up the frame with a torch and then rubbing peanut oil on it also works. has anyone used either of these methods with any long term success?
