It’s no worse on any particular color, black just shows imperfections more than any other color. Mopar paint isn’t particularly bad, all manufacturers’ paint is softer now than it was years ago due to environmental concerns. A proper 2 bucket wash is the way to go to keep swirls and light scratches from dulling your finish. Since most people can’t do that every time, a good product like ONR is a good alternative. Certainly much better than any automatic car wash.Loos like my reply from work didn't go through earlier, but I had mentioned that I picked uo this stuff and a good wash kit from Autogeeks for a great price! BTW someone said it was a bad idea for black paint, especially the Mopar variety... I'm curious to know your thoughts/experience on that as a detailer?
