I did the same in my bathroom. Well sort of. I covered the two bulkhead walls and the black tank with that material in my bathroom. Keep in mind those are flat surfaces. It worked well enough in my application but honestly its not the the best to use.
I would not repeat would not attempt to use this on any curve. The material is too thin and will not lie down properly. I think you will be disapointed if you try it that way. It will buckle and look like hell.
You can buy the good stuff at Vintage trailer or others. If you want it to look processional thats what Ide do. Your mileage may vary.
