Detail spray effectiveness works in direct correlation to the condition of the wax on the car. A recently waxed car will allow most good detail sprays to glide off easily. If your car needs wax, the microfiber towels will drag.....
No wax on my car yet other than the first Rain-ex wash with beads, the blue stuff and whatever it was cut with. Stay on top it from day one and not an issue. I do dust it off the first with a California brush.
