Also, the video was for demonstration purposes and he was speaking to explain what he was doing and why which causes it to take longer. As far as 'absolutely zero possibility' of doing them in under 30 seconds, I can speak from experience that it is absolutely possible, especially if the tires are clean. You may use a little more product so it spreads quicker, but even with tires > 35" I have no trouble doing it in that amount of time when I'm in a rush (minus 6-8" across the bottom of the tire that I tackle later after rolling the truck).
