A spray-in bedliner is a permanent coating
that bonds to the truck bed and cannot be
removed. Promptly rinse the bedliner surface
following a chemical spill to avoid
permanent damage.
Spray-in bedliners can fade from oxidation,
road dirt, heavy-duty hauling, and hard
water stains. Clean it periodically by
washing off the loose dirt and using a mild
detergent. To restore the original
appearance, apply the bedliner conditioner
available through your dealer.

Vehicle Care
Caution
Failure to clean lamps properly can cause
damage to the lamp cover that would
not be covered by the vehicle warranty.

Using wax on low gloss black finish
stripes can increase the gloss level and
create a non-uniform finish. Clean low
