This is a good review of Adam's products, but I have to disagree with your contention that Adam's is expensive. After using Adam's for many years, I have discovered the following: 1.) Adam's is much easier to apply and remove than most other products so it saves a lot of elbow grease. 2.) After your first detail with Adam's, you use a lot less product to do your vehicle than anything I have tried, hence it lasts longer and goes further, making the initial cost lower because of using less product per application.
