I don't work for or run a detailing business so no money is made from what i do. I agree people can do as they wish and use whatever products there is. Andy commented that i should give my advice so i did, i don't think i ever said they can't use waterless products.
T-cut has been on the market for so long because most people are not educated in the other better products out there.
Chris, i didn't realise we were pals? Not blowing my own pipe one bit here. When i was a regular on the forums there were many people praising my work or asking me to detail their cars, was just letting the newbies that have commented know that i have some knowledge in cleaning products.
