If you can get to a Motorcycle shop in your area ask for Simichrome Polish. The tube comes in a Red and yellow box. It's an excellent metal polish.

I tend to use fine wet and dry paper to remove seam lines etc and then finish with a small circular wire brush in my como drill (dremmel type) clearcoat if you wish afterwards.
