I'm glad this thread popped up. I spec'd the factory spray in, but now that I think about it I'm not sure I really need a bed liner at all? I'm getting a Bakflip VP hard cover and a mesh net to throw groceries in the back, otherwise it'll likely never have anything more demanding than a bunch of hard luggage and baby car seats. When I take it to the sand dunes or any aggressive driving, the bed will be empty obviously. So with it being covered always and out of sight, I'm not sure why I would care about scratching the paint in the bed and when it does get scratched up, I can always DIY the Raptor Liner for $400 savings or have LineX do it later. I definitely would prefer to save 3 weeks off my delivery time.
So, with light bed use expected and a hard cover always on, any real reason I should get a liner right now at all?
