The rubberized coating that was put on the roof was extremely hardened and wouldn't budge with a wire cup wheel; it would just smear. We tried a heat gun and putty knife but it took too much heat to warm it up and warping the roof skin was a concern. Finally, this disc did the trick. The key was not to drive through all the layers at once but do keep moving around and take one layer off at a time.
