It's just a fine brush on the other trim. I used a gray pad to do it. I was wanting a satin finish more than a defined brush finish, and that worked well on the hard SS.

I was considering polishing the wheel to remove the oxidation and then trying a dry wool polishing pad on my 7" polisher/sander. Maybe that will give me a uniform satin finish if i can put the wheel on a lazy suzan and rotate it slowly as I buff from the center out to keep the scratches in a circular pattern. Thoughts?

Anyone ever tried a chemical like oven cleaner on aluminum to etch the surface?
