I literally just detailed my car yesterday and the claying process was a pain. The hard water here left spots all over my car and a single pass from clay wasn't enough to remove it in some areas. I also find that clay can leave strange streaks in the finish which was a bit disconcerting. Part of the PIA of owning a near black car. Took me 3 coats of Z5 to remove most of the scratches and swirls in the paint. Thanks dealership!
This pad looks like a major time saver IMO. I also really need an orbital polisher. Doing 3 coats by hand is painful and takes forever. I really wanted to add a last layer of Z2 but I'm too sore and tired. Haha.
