TOUGH.
"I had Rhino Extreme sprayed on my GMC Sierra by Krown Kitchener, and I was very impressed by the quality of the work done. The liner is absolutely gorgeous and the service was top notch. I am a brick layer and do NOT take it easy on my equipment. It doesn't seem to matter whether I am throwing bricks, gravel or scaffolding in the bed of my truck, the liner stands up like nothing else. I would highly recommend the Rhino product and the service from Krown Kitchener."
