Anyone tried sanding/filling their rear window trim with a body filler, then priming/repainting them black? Mine look pretty rough in some spots but are still solid, what kind of filler would be flexible like the rubber moldings so it wouldn't crack or come off in the near future? I kow you can get trim covers from steeda, but only for hatchbacks and I don't want them to stick out at all.
