to be fair i work as a valeter and our company uses this product on customers cars, it does do a fairly good job but overall i always use other stuff on my car, Nielsens comes out a whole lot better and so does zymol, i use it at work but like mike c says theres a whole lot better stuff out there for around the same if not slightly cheaper price.
good for budget wax, but i would use a different one if you can afford to stretch a bit more
