Products like Dupont, Turtle Wax, Mothers etc. will all remove scuffs or blemishes. They will do this because they all contain abrasives and solvents. What makes products like Menzerna and Poorboy's different are the quality and uniformity of their ingredients. The finished product is more reliable and much smoother which results in greater shine. Maybe DI would like to chime in on this one also.
