1973 Plymouth Duster - Grill

I just pulled the headlight cowl, grill, chrome plymouth upper trim and wanted to get some guidance.

I was going to 0000 steel wool the trim and the cowls.
Clean and paint the grill.

Any advice on the best chrome paint to use for the grill?
Can I paint the Cowl to match? What about just the inside?

Sorry all just kind of a newbie here. Thanks in advance.

I believe the factory color on the grill is argent silver. There is a Mopar brand in a spray can. Comes out great.
