Meguiars, Mothers or Clay Magic Clay bar system. Any of these will be good. I buy what's the best deal because I go thru so much of it. Use the clay bar whenever the paint doesn't feel silky smooth to your touch anymore. Then use a good carnuba wax or a good synthetic wax. If your car stays outside and/or you live in rough climes, consider a good sealant. Griots Garage's website sells two versions, both good. I use it on my NB since I have no garage. Get yourself a good wheel and tire cleaner. A heads up: Use a tire shine product that doesn't include silicones. Buy a water based one if you can. They are better for your tires, not causing "brown" build up. There are a plethora of good products for the interior. If you have a convertible top, buy a top cleaner. Try using soft microfiber towels on your paint. One big one for drying. one for waxes and a separate one for windows. Don't wash them together. You are in business!
