I am using the low end Griots 3 in 1 Ceramic spray (2 coats as directed) and after a good paint clean up. Griots also sent me some free Cermic Wax when I inquired about some of their other products. I was told to always make sure NOT to use a wash/Wax car wash soap but rather a PH balanced one like Meguirs Gold Class. I was wonder if the same held true for a detail spray.
