Slow91,
If you like the "brushed" look, use WD-40 and some steel wool. It makes aluminum and stainless look awesome and nice and even. Cant see the sanding marks. I saw a guy , years ago, do this to an entire Big block Blower engine. Blower,valve covers, manifold, everything. It won best engine compartment at that show.
Just a bit of info.
