Tryed the P21S concours Carnauba Wax along with the p21s paintwork cleanser as a prep. I am very happy with the results. Claybar if needed and use the paintwork cleanser and then the wax, follow directions, it is very easy to use and really enhances the shine. The Germans really know how to make a quality wax. I got mine on Amazon.com or you can get in on Autogeeks.:beach:
