"Dune Junkie".....Sorry to veer off of the original topic. I looked online at the product and the website concentrates on selling the product(s), but no where does it talk about how it works.
I have a new coach with new paint, that has a lot of black in it, I'm very particular and try to do whatever I can to keep from scratching the paint job (micro scratches). Washing without a fair amount of water or re-using a wash rag over and over again is something I steer away from. I use only lambs wool on the painted surfaces.
