 We were ready to film this. And by the way, there's a video of this whole experience on the RoofMax website and the RoofMax YouTube channel. But he came out a couple of days ahead of time and sprayed half the roof. And then when we got there with the crew, we actually went up on the roof. And you could see literally before and after how one side of the roof was very brittle and stiff and the other side.
