Radiator Finish

[jamesg602]

I have a brand new Be Cool radiator in the box and was noticing the top part of the radiator has a few nicks/small scratches. I was wondering if anyone may knows how to get rid of these, I would like to keep the natural fininsh and am trying to stay away from the "bling." Is there a way to to get rid of the scratches or polish the aluminum without making it too shiny?
