I have both the ice polish and the liquid claybar. I bought the claybar product before I saw another thread on here about the product. In that other thread the liquid claybar was trashed by just about everyone. So I figured that I had wasted $15 before I even used it. I figured that since I had it and I was too cheap to go out and buy an actual claybar I decided to give it a try. I used meguiar's car wash, dried it with a microfiber cloth and then applied the liquid claybar and then washed again, dried with another microfiber cloth and then applied the ice polish. I followed the directions on the liquid claybar and the polish and my car looked great. There were some scuffs on the clearcoat which are now either gone or have been removed enough that you'd have to know where they were to find it. I had no traces of residue because of the wash after the liquid claybar treatment. Just rinsing it would not be enough because it does leave a haze on the paint.
The finish on the paint was much smoother than it was before so I would say that the liquid claybar accomplished what it advertised, so I am satisfied with the results. Some people don't mind spending 8 hours detailing their cars and have them come out looking perfect, I would rather spend an hour and a half and use these products and end up with a car that looks great in my eyes, thats all that really matters anyway.
