I have a non-ferrous metals scrapyard not too far from me. The guy there has a "gun" that'll tell you the composition of any metals that he points it at. Pretty nifty. Maybe I'll drive over there and check it out.

They do seem rather tough for such a thin gauge of metal. Maybe they are kryptonite after all? I'm seriously thinking about polishing mine now too. They don't have any real scratches on them, so a pad and some rouge might do the trick.
