What are you guys using to polish your dually simulators?

I'm trying to get my truck cleaned up as much as possible for a show on Father's Day weekend. The whole truck needs a good polishing/buffing anyway, so the show is a good excuse to dedicate some time to the truck.

I went at one of the rear simulators with "Never Dull" and I'm NOT impressed. I believe the simulators are OEM stainless steel (1992). They did get a little brighter, but they just look like they are full of hairline scratches. What to do... What to do?

Mods, feel free to move this to the question and answer section if you think it belongs there. I just thought it might get more action in the truck section.
