Sounds like marring to me...
On soft soft paints i often get marring where the paint has a slight cloudy look in the paint. Usually i can see the overlapping of the buffer.
Usually this is caused due to the pads being too aggressive.
The green pad has heaps of cut. Using that with
Klasse would have caused the problem.
Go over the paint with FP11 with the softest pad you have. probably the white pad.
Then check the same sections again. Just do one panel and cheap.
Apply the klasse by hand.
