Patman's right. I've got a Rhino liner in the bed of my T100. It's pretty thick on the bed, but the rails are a bit under protected. I cut the liner on my rails with a dog box, the lifetime warrenty takes care of it, but it's a hassle taking it over to the shop. A guy at work did the "do-it-yourself" bed liner and his truck looks pretty good, although the bed coat isn't as thick as mine. Had I had a garage and the time to do it, I would have done the do it your self route just for kicks and to save money. Go for the do it yourself kit man and enjoy the "quality time" with your truck ;)
