For guys having swirl problems, you should look into this sort of resin that certain detail shops can apply. It's a sort of polish that dries rock-hard. Sorry I'm blanking on the name of it, but a friend of mine had it done on his black car, and even going through car washes, it has remained swirl-free.
Not sure how long it lasts, and it cost him $450 to put it on.. but he has been extremely reckless with washing his car for the past year and it still looks great. I wouldn't own a black car without something like that.
