To be honest PA products are not as much as you think. Their products are very concentrated and therefore your using very little. Also like someone else said PA products are ahead of the curve in many ways, for instance PA Engine. An engine cleaner that cleans and dresses in one step and decreases better than most undiluted APC's. How much better does it get, especially when your working on high end cars and you don't want to soak it down with water. The same applies for a lot of their other products, say ahead of the curve.
