:idea: As a winter project I've decided to smooth and paint the Gray trim on the truck black to match the color of the truck. My local body shop has been of no help to me as far as smoothing the surface and removing the ribs goes. I would welcome any ideas or tips that those of you who have done this on your own trucks might have for me. From what I can tell if you sand down the ribs you will create a hole as there is not enough material under each rib to prevent sanding thru the piece. Is there a source for smooth replacement pieces? ( side steps and rear bumper trim.) Any help would be greatly appreciated. I also plan on doing the rear window trim, tailgate handle and mirrors also.Thanks
