The best product is the 3m perfect it #3 cleaner clay part#38070.
For best results get some good quailty car wash/water and use to keep the clay wet.
Do this in the shade as well, use it on your glass also. It will shine like a new diamond. As you clean the car look at the clay for dirt and make sure you flip it over from time to time. The clay will conform to the angles you rub. When done get yourself some good polish
not wax. I use 3m perfect it polish or liquid glass it has no wax. My car shines like a gem. Try it you will like it. Do this every 3 to 6 months. Your paint will love it and so will you. Let me know your results.
