LOVE the title!
I've used (and will continue to use) MOTHER'S BILLET POLISH. It's fantastic for hardware. Auto parts stores carry it.
You can use the Maguires (sp) Plastic Polish on metal for a finer grade of polish, and it also removes minor scuffs and scratches from poly finishes quite nicely.
Flitz is also just fine.
