All Iron Bull Bumpers are coated in our “Black Shield Coating”, a tough spray in bedliner material. The Black Shield Coating was chosen because of its ability to resist rock chips, road debris, sun fading, and its ease of repairability in case of an accident. Most other bumper companies will coat their bumpers with powder coating, but powder coating can chip and fade from everyday driving and can not be repaired easily, because powder coat has to be chemical stripped and recoated. That’s why we use our Black Shield Coating.
