You might try the H.A.M.B. site. If not already registered there it's a painless 5 minute process. Search the title "Raising the Dead in Dr Bluto's Lab". Gives all the hot poop on using certain acid techniques that the "authorities" use to bring out altered, or rust eaten vin's on pitted frames. I would first try the wire brush, light sand paper etc first. Hope what ever you find matches what you have. Good luck
