Paint correction product?

[mattbta]

While my Escalade roof rack is being painted to match, I've got the original Tahoe LT rack removed. There's some light oxidation on the paint, a little cloudy. Would like to make a few passes before putting the Esky on to get it in shape.

I understand I'll need a DA polisher, but what products? Years ago when I bought a black 98Z28 new, I had to do some light correction and used 3M Perfect It and 3M Finesse It.

What are the products I should use, present day?

Any tips or recommendations welcome.
