Look for the build date (some where on the drivers door) because I've been told not to wax a new car till 6 months after its build date. Clear coat is not hardened yet. The clay bar is great for an older car that has many years of neglect done to it. It does feel like its been waxed after you have clayed it. The kits do cost a bit, you may get two to three cars clayed before you notice the color of it start to change. I've gone to Meguire's now and love the look. I do two coats with a hand buff and then one coat with the orbital buffer to the top and hood, seeing is that they a get the brunt of the fall out.
Ask a detail shop if you don't get the answers you trust.
