Rocker Panel Cover Help

Thanks for the reply. I was lucky, I had to use the buffing wheel on the wheel well openings, window trim and the fender spears.
The rocker panel covers on a 66 are heavy Alum. extrusions. They have several deep wide grooves. The bottoms are painted black. The tops are highly polished. I'll sand the worst areas and repaint the black.
Thanks,
Mike
