Take it off and give her a good polish. Not by hand but with a polishing wheel. A friend did mine a couple of years ago and it looked like new.
Was going to say, it is polished aluminum, not chromed..... A good polish and you should be great. I have to do mine at some point.
There is a clear coat on it. How hard is it to remove? More importantly... how hard is it to GET BACK ON?
