Please don't use all of Chemical Guys stuff. Most of its over-hyped garbage with the exception of a few products. Invest in some real polishes and compounds from Menzerna. BTW, the whole hex-logic thing is a gimmick. They are at least $1-2 more and don't work as well as a flat pad. The max pad size you can use on a PC is 5.5 inches. See link below.
