For those of you that have never tried claying your car, you are missing one of the most important steps in getting a fabulous shiny finish. Also, convince yourself with this little test: Clay the WINDSHIELD of your car and you will be AMAZED at the difference. Removing the surface contaminants lets your polish and or wax adhere much better and will result in a deeper look. New cars that are transported by train are notorious for have "rail dust" imbedded in the clearcoat. These look like little brown rust spots. Claying removes them. Also, claying is easier and faster than waxing. Every new car should be clayed to remove the surface contaminants from the train tracks "rails" and road contaminants from the car haulers. Then polish or wax to keep it looking good. Wax acts as a sacroficial coating that gets eaten up by sun, rain, acid rain, washing....and all the things that would first attack your paint.
