If that doesn't remove the swirls and light scratches, step it up with wolfgang and a medium cut pad such as an orange lake country pad. Remember, technique is very important too.
I don't know about BMW paint being hard. Jet Black is super soft. You can mar it by putting your bare finger on clean paint. Your bare skin will scratch the paint! It is a real pain in the ass to keep in good condition and I use some elaborate wash techniques to make sure it stays good.
I don't need to use anything stronger than Menzerna SIP to correct anything and most of the time I can get out a lot of stuff just using Prime Strong on a DA.
