Hmmmm ... Before claying, I always do a wash, then a thorough, Autopian drying before I clay. My reasoning has been that I don't want to risk any water spots. Am I wasting my effort by drying? :nixweiss Be aware, though, that a typical clay job takes me about 3 hours. I'm slow. But I'm assuming if the car air-dried, the clay wouldnt remove the water spots. Is that correct?
