I have an 2019 F150 and would like to know how to polish the black plastic center pillar covers. These are the glossy black plastic covers that are between the front a rear side windows. Mine are really glossy, and they have very fine scratches on them, and look all smudged when in direct sun. I have hit them with Megs ultimate polish and a RO polisher with a white pad, but they still aren't great like new. I am just a hobbyist wanna be detailer
