Glad to hear overall the detailing went well. You certainly can remove those deeper imperfections in most instances however it may not be worth the time and effort though. This is particularly true with many of the black BMW's because it seems to be such a difficult finish to work with for those who want perfection. To remove them you'd need to use a more aggressive combo which creates more haze which can be challenging to remove. You could try using the SF 2500 with purple foamed wool pad or a surbuf pad but you'll need to follow that up with SF 2500 (orange pad) and then the SF 4000 and a white or black pad. If the SF 2500 is not enough then I'd suggest the M105 with an orange pad or you could go all the way up to the Surbuf R Series MicroFingers Buffing Pads
. This would help get rid of the majority of the fine imperfections, if they are any deeper a rotary polishing or a light wet sand would probably be the next step. Again my concern is with the black BMW paint it's generally harder to remove haze left over from these more aggressive steps. If you do try any of these please make sure you use them on a small section first before doing the whole vehicle. Good luck!
