I actualy do paint and body for a living so i got fine and coarse scotch brite . I use the coarse and yea it works fine we even sand blasted the header after fixing a couple things we wanted changed . after that it looked ruff just used a scotch brite brought it back out . Im not sure how nice you want it to be but for a header it looks good and it all looks the same no burnt spots or different shades. I would advise sanding it just my opion .
