Well my truck is starting to get chips and minor surface rust in a couple spots on my rocker panels. I am getting ready to touch it up and am thinking of putting chip guard or bedliner to provide additional protection. Some say the bedliner would be harder.... what is everone else using? ---------- Post added at 10:01 PM ---------- Previous post was at 09:15 PM ---------- ok... I believe I have made my decision.... I am going with POR 15. Plan to prep and spray the underside and rocker panels. Have to keep that darn rust away.
