Get yourself some purple polish and try it out, 10 times easyer than mothers polish. We use this stuff on our dumptrucks wheels and tanks and I can do everything on one truck in an 8 hour day. You can find this stuff at Kenworth dealerships and probably other big rig dealerships or online here.

Once the parts are shiny to your liking you can apply zoopseal to them and they will stay shiney for a couple years. I did a set of wheels and ran them through Michigans winters and they stayed shiney until I sold the car. This stuff is a little expensive but it does work.
