Had to have body repairs to bed of my truck which entailed having the bedliner redone in areas. Received truck back from body shop and noticed bed filled with small tiny rust spots not only in flat portions of the bed but everywhere including the tops of the wheel wells. After showing conditions to other body shop people concensus of opinion is that while in body shop someone ground on something close to my truck with a grinder causing hot particles to imbed into the plastic finish. Now the metal particles are rusting. Hard to tell depth of the rust spots. Has anyone experienced this situation and have a solution other than replacing the entire bedliner.
