I moved some crap out of my sister's house (she's moving) and found the whole Griot's Garage kit in there. Knowing my sister will never wax a car in her life... I took it home and tried the clay. The clay picked up some dirt... helped a problem area or 2, but for the other 98% of the car, I really didn't notice much of anything different than a regular compound job. I must say, this Griot's fine finishing polish is amazing. It looks better after this stuff than the wax i've been applying. I can only imagine 2 things after I put their show-finish wax on. 1) How tired my arm will be. and 2) How nice it'll look.
