Riding yesterday on freshly graveled roads, my Spyder looked more gray than blue, and was covered with the road dust. I used S100 and the whole process, including drying everything, took me less than 30 minutes. The only glitch was in the very lowest portion of the windscreen where I could not get my microfiber cloth to get to it, the water had to dry by itself. But for as large a vehicle as the RT is, it took surprisingly little effort and time to get it clean and shiny. I give much of the credit to S100, a product I have been using for many years and am more than pleased with it (as long you rinse it off really, really well).
