If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection.
Original manufacturer replacement parts will provide the corrosion protection while maintaining the vehicle warranty.
