I think the hammered paint is made by rust-oleum. Just go to the spray can section of a store and look for a textured cap. The hammered paint is pretty cool if you put it on a few good coats of it.
You could buy some roll on bed liner from a store that would protect those plastic fender flares. Its usually about $100 a can as far as I know. I have a friend with a jeep that bedlined the interior and covered the exterior pannels over the wheel wells. IT looks great and its really burly.
