Any experience with Rhino liner?

Rhino doesn't get as hard as does Line X, as it stays more rubbery to the tough. Which there are both pros and cons to that. I haven't used it on a roof but do have it in the bed of my Chevy pickup. That cost was just over $400. There was a lot more metal preparation than I would have thought. The paint in the bed had to all be roughed up so the Rhino would stick. The sound of grinders running on my new truck was about more than I could stand to hear so took a long walk from the shop, till they finished. Dries to the touch in a few hours and they recommended 24 hours before hauling anything in the bed. I am considering having my inside Jeep floor sprayed with the stuff.

I don't see any problems with using it on a roof, so long as the surface is properly prepped.
