I have the HD Cleanse and Titanium wax. The wax is worth buying but HD Cleanse is a bit of a gimmick i think...be skeptical of the marketing crap they give you for some of the products as well! e.g. the Titanium stuff is supposed to be very durable but the car stops beading from anywhere below the shoulder line after a week or so of applying.
Im using the Zymol shampoo!
