The beginning of the end for the finish on many cars and trucks is an improperly stowed load. Invest in the appropriate racks for bicycles, cargo, and luggage. A good trick to keep tall objects from sliding around in a pick-up truck bed is to use a shower curtain rod as a brace. Just push the cargo against the front wall of the truck bed and install the rod behind it and twist to secure. Cargo nets will also help keep objects from banging around and damaging a truck bed.
