I had heard of other people claying as they washed their cars so I figured I'd give it a try. Worked like a charm. Took me just over an hour to do my very dirty 02 Altima. The soap provided plenty of lube. I would wash a section very carefully since it was so dirty, clay it, then go over it with the soap pad one more quick time. Saved a lot of time over doing the steps separately. I'm going to do the Durango tonight, even bigger time saver!
