Black Car and SIP Oily Residue

[Rsurfer]

Black C6 here also...sounds like we have the same issue here..a few minor scratches here and there left over....curious as to the feedback...(noob to this whole machine polish stuff)

You can move up to Menz Power Gloss or Meg's 105.:buffing:

Still have a few fine scratches left in black surface. Not sure if they are worth chasing. I wnated a mirror like finish but not sure that is possible with a black car.

Yes, it is possible. If you truly want a mirror like finish then you'll have to do as you said and chase those fine scratches. If your polish doesn't have enough bite then I do as Rsurfer suggested and jump up to Meg's 105 on a white pad. That should do the trick for you. I've seen a friend of mine polish a black door to perfection using 105.
