I tried CS a couple of days ago and i'm not sure about the results. I followed the directions and misted the applicator that came with the CS. First of all, it's hard to know if you are putting any on the car or not. Are you supposed to see it when you put it on? I let it sit on the car for about 24 hours. When I returned I could still see it on most of the car. Maybe I applied too much but how are you supposed to know if you're applying it if you can't see it? I used Z6 and buffed off the CS. After I was done buffing the car looked great but i'm not sure there is much difference than just using Z5 or Z2.
