sets fast and dries quickly. Dries perhaps too quickly. If you don't squirt it out of the tube quickly it will dry and clog the tube because it mixes inside. They provide 3 applicator tubes but that is not enough for the amount of product they give because you CANNOT REUSE the applicator tubes. It does dry nicely but there is not much time to work with it and use the sheet of plastic to mold it ir set it where you want it.
