I believe the factory bed liner is LineX . I have had this in my truck and Rhino liner in a previous vehicle. Over time, the Rhino chalked a black substance that would get on your hands and bed contents. In my humble opinion, LineX is the best spray in liner available. The U.S. military uses LineX extensively to protect their vehicles and equipment. The bed in my truck and 1120 look just like the day I got them - except a little deer blood.
