Which would you choose prior to polishing? I'm thinking it depends on how the paint "feels". I have both, bit only used the PCL before waxing this past weekend. I did use the lotion with white pad on a DA. I only did the hood and trunk on my red Z4 roadster, but it obviously removed a bit of haze. I'm betting the clay bar wouldn't do anything about the haze. So how do you decide to clay versus cleansing lotion?
