This stuff is fabulous, both in looks and to work with. Cuts like butter with a wet tile saw, but be prepared to have to glue a few small pieces back to the stick-back, nothing terrible. And definitely rinse it, its got a good coat of dirt on it and looks much better once rinsed. Rinsing and cutting dont mess up the sticky back at all either, very nice. There are some little glue spots but they easily peel away as well.  Overall, great product for several projects.
