Great product! After finally using it as directed,... ...it removed everything from the roof of my new Honda (especially the sun baked overspray from a minor repair.) Missed a stubborn patch, so I guess I will use some clay as I want to save my new mitt and avoid marring. May just use the mitt as my big gun for prep and use my clay for 2 minute detailing of small areas where I don't want to have to worry about cleaning and drying the mitt.
