I was removing some water spots from the rear windows and also did some of the lower section of the rear spoiler. This is the shadowline black plastic part that runs along the bottom of the liftgate spoiler and down the both sides of the rear liftgate window. The clay bar removed the water spots but it left behind some marks from the clay bar. No scratches. I tried some detail spray, but it didn't help.

Since its gloss black painted plastic, what can I use that will remove the clay bar marks without harming the gloss black plastic? Thanks
