Got a new ride, Hyundai Tucson 1.6T in Black. Last car was white and easy to keep clean, or at least looked clean. The black is going to be a high maintenance car but after discovering Optimum products being used by Detailers on line I feel that I have found a solution to the problem. Started with ONR and liked the idea that I could clean my car without using the hose. Have done it twice now and the black shine is wonderful. My driveway is full sun so working on a panel at a time and drying it immediately solved the problem of water spots which really show on the black. Will explore some other products by Optimum.
