He went from being very technical to making some silly claims about polish in a car wash (is he really expecting a liquid applied polish in car wash, to smooth out the paint?). Tri-Foam that is three different chemical makeups? 20 years in the industry and I've never seen this. As for his "test" at the end with the microscope, this is the most ridiculous part of all. Any detailer worth his salt knows that paint is porous and if you really want a "clean car", the surface needs more of a deep cleaning than a car wash can render. I can take a brand new car with shiny paint, just delivered to a dealership, and do the same test he did on that car and have it look "dirty" under a microscope. I ran detail shops for years at car dealers, almost every new car we cleaned up for delivery was clay barred to remove all dirt (this was after hand washing) so that we could put a coat of wax on a clean surface (you wouldn't believe the amount of dirt and rail dust that will come off new cars). His conclusions are nothing, but a hack job.
