Haha, I was just thinking about this myself. As I live in a very humid area, near the coast, everything that isn't painted corrodes or rusts. My shift lever is getting a a bit nasty looking. I was thinking of coating it with some Breakfree CLP(or whatever it's called now), but I don't think it'll stay on while riding. I might just pull it off, clean it, and hit it with a few coats of clear.
