was reading my Porsche Panorama magazine and noticed a couple advertisements for Zymol and P21S. i use Zaino on my P-car and have had impressive results. i have used Liquid Glass on my Maserati and Benz also with good results but it appears Zymol has a product line just for P-cars. Anyone using Zymol or P21S? would be interested in your review of the product. I did a search of the forum but did not find much,
