This is kinda unrelated, but...
To remove small scratches on the ipod screen, ppl use a little brasso to polish it. Apparently it works like a dream.
Or, you could try using Meguiar's scratch X - normally used to remove little scratches on cars.
Ok, I really have no idea how both with work on the bass - so unless other ppl second these suggestions, I think it's better not to try them
