I'm not trying to put you down in what I'm about to say, so don't take it the wrong way. With black cars, especially
BMWs and their incredibly soft paint, ONR will induce scratches eventually. Maybe you've never seen your cars under the proper lighting (e.g. metal halide) to see what I'm talking about. BMW's powder-based paint system is environmentally friendly, but is rubbish in terms of performance.
