I've had nothing but great results with all of Adam's products. Living in California
and the drought, I use their Rinseless Wash a lot and their Detail Spray is one of my favorites. The have a new H2O spray sealant I am going to try this weekend as well.
If you were not happy with the product, you can email them or give them a call. They back all their products 110% and the customer service is top notch. I am on their forums there and learn a lot from other users of the product as well as the videos of their products.
