Scuffed window trim

I'm in the process of getting my 4-door blazer prepped for paint. the rear side glass is a pain to remove so i decided to do some sanding with it still in. BIG mistake. Now, because of a few extended stokes with the long board, the black plastic/rubber seal around the window is scuffed with 80 grit. Is there any way to repair it or make it less noticable? or am i going to have to buy all new trim?
