Adams is all I use, so I know you will like the products. I would recommend using 2 oz of the All Purposes Cleaner and the car shampoo to wash the car instead of Dawn. The All Purposes Cleaner is what will help remove the old wax and what may be left will be removed with the clay bar.
This reminded me that I believe Adams is presenting a detailing clinic featuring their products at WCC this Saturday (4th). Also heard that the obligatory discounts on their product line will be abundant.
