Grill help

[plowro8]

Trying to figure out a good way to clean up this grill and get some of the dents and scratches out. Most of the anodizing has worn off, but there is still some in hard to reach areas. I have taken advice and used Mothers polish, as well as testing some 1000 grit sandpaper in a small area, but I am just not happy with the results. I figure it would probably be a no-no to paint it... Maybe I just need to live with it the way it is? Any suggestions appreciated. Thanks
