recently repainted my bumper and trim and roof in black bedliner, was so happy with result I'm thinking of redoing whole care in paint, have a spray gun already, just a few questions... I have some chips with rust spots, do I just sand and prime or do I need to place a rust preventer prior to painting? hopefully not as I covered spots on roof after sanding back to metal with bedliner. advantage of bedliner roof though is no worry from scratches when loading it up. how hard is it to repaint vehicle, I found the fenders and trim was easy easy but I just rough sanded and used bedliner..... ill post pics as soon as I figure out how to later...
