Just wanted to see if anyone has any suggestions to prevent the interior-side of the tailgate from getting dinged and scrathed up from items in the luggage area. Im usually pretty careful about this stuff, but I recently noticed that my tailgate's interior sheetmetal is starting to get scratches and already has a couple of dings. A buddy of mine suggested Rhino-Lining or Line-X. I got quoted 150 bucks at my local Ziebart and they want to take my tailgate off when they spray it....im not to sure about this. Anyone have better suggestions/solutions?
