I have a touchless automatic wash. I have 2 local chemical suppliers in my area that can service my chemical needs. They are diamond shine and warsaw. I have read the numerous posts on warsaw chemicals and most people seem to be happy with them. I don't see hardly any post on diamond shine chemicals, which is what I currently use. Am I the only one using diamond shine on this forum? I would like to hear from people who are familiar with both and get your opinions on which you like better. I think diamond shine chemicals cost a bit more, however I am more interested in getting the best wash for the buck for the customer. I currently use fresh-n-clean presoak, bead up drying agent for clearcoat protectant, sensations triplefoam conditioner, cherry foam for foaming brush, and hp soap, and I am about to add weatherguard.
