Waxed the car and found the top surface not to be smooth when you run a rag over it. so I got a clay bar kit and used it for the first time, very simple to use. You can feel the "traction" on the paint go away immedietly, now the rag will fall off the car by itself its so smooth, no scratches. I use a "california duster"[here we go again] all the time and that may have contributed to the paint roughness, now it looks and feels like it just came out of Jeff Millers shop. By the way, its about 80 here today, had to resort to shorts !!
