What's the best kind of pad and polish to use with a DA polisher to remove some light oxidation from the rear bumper cover?

 

3M polishing compound ....... I have used there product on just about every thing I have.
headlights , guns , non clear coated aluminum wheels, my car ,truck , mower, coins etc
be careful using power tools when polishing .....don't get it hot by staying in one place to long
and be sure that you have a good even coverage so you don't end up with swirl marks
