Looks good and goes with the rest of my diamond plating on the truck. Very thin material and product was bent when arrived. Tape did not stick to tailgate and not enough screws came in the box. For as thin and cheaply made as it is, it should be marked for half the price. OK for a show truck, but if you really want to protect your tailgate and use your truck hard, I would not buy this product.
Exactly what I was looking for

I didn't want to pay $500 just for the a whole new bed liner so I went with the Dee Zee bed mat and this Dee Zee tailgate protector and I was very impressed. Not only does it protect my tailgate from scratches but it also looks great on the truck. I did not receive any screws with my product but I just used two self tapping screws I had at the house so it wasn't a big deal. Also both corners got a little bent up in shipping but it wasn't a big deal, I was able to straighten them out by tightening a 2x4 on both sides. RealTruck has a great customer service department and i know they would have replaced the cover with no problems if i told them what happened, but i figured it wasn't a big deal so why make more work on both ends. The cover is a little pricey but in the end it was worth the purchase.
Fit perfectly

After I straightened out the bends,( from shipping) It worked fine. The two sided tape does not stick to the stock tail gate cover, painter balck pop rivets worked great.
