Roo: A spray on bedliner is a tough, thick, sandpaper feeling paint that when applied right is put on nice and thick over the existing interior of the bed. Plastic bed liners just drop in basically, no need to paint, and I believe they are cheaper too.
Correct.It's a Jeep thing, you wouldn't understand.
Yeah, it's fine to do that on a truck, especially one that sees a bunch of off road duty. But only up as far as the lower trim pieces. It stops little branches, rocks and mud from scratching your lower doors and what not. Though it is a case by case sort of thing. And the guy with that Audi better hope that never fades, because that is the last "paint" that will ever be applied to that car. I bet it's thick as or thicker than a coin.
Truckbed= Yes
Undercarriage of a vehicle used for offroading= Yes
Exterior paint of Audi(Or any car for that matter)= Just plain wrong.
For added hilarity, Google "rhino liner" and "hootus". Possibly NSFW language.
Oh damn, now I'm not going to get to sleep for a while Duke.
