I have BSM and it may be hard to keep clean but the previous owner washed it once a week and I have continued this throughout my ownership and I have no water spots. Is it hard to keep clean? Certainly... but if you take the initiative to wash it frequently you can keep the paint in pristine condition. It's when the hard rain has time to damage the paint that you run into problems. For me, the look of a freshly cleaned black car is totally worth the once a week wash. Roughly an hour out of 168 (hrs in a week) isn't much to ask for, really.
