You can get it in widths of 2" to 6", lengths from 10 to 50 feet. It has a layer of vinyl on it. You can also get it with aluminum layer for Airstream TT's. It will work with rubber (EPDM), TPO, aluminum and fiberglass roofs.
Clean the area with mineral spirits, remove any excess with a dry rag, remove the backing, and lay the eternabond, once it touches it is stuck, get the roller with it and firmly roll it down. Eternabond recommends using a thin bead of dicor around the edge.
I just did the front of my TT on Tuesday morning. I had a small opening in the dicor from shrinkage and a couple of places on the front trim piece of the roof where the trim was showing through the dicor. I covered the seam from one side to the other. It was kinda hard getting it to lay perfectly, but I think it went well. I ordered 6" x 50' from amazon for about $90.
