Ok, im going to be doing a suburban bvuild up in the near futue and dont want to do a 2x4 or 3x3 or whatever rocker. id rather do a slider underneath the rocker. question is, how do i keep my purdy rockers rust free. if i remember correctly chevy made a big mistake and those rockers collect mud and water, no? anyway to keep them rust free? other than por 15?
