Depending on your skill level and expectations, Menzerna 106fa may not have enough cut to fully remove the compounding marks. I personally like to use Menzerna PO83 Super Intensive Polish after compounding on a Lake Country White Kompressor Pad. I would then use 106fa on a Black Kompressor Pad to remove any hologramming.
If you would like to stick with PO106fa, then I would recommend using it with an Orange CCS pad (the more aggressive pad will help the 106fa remove the compounding marks) then try PO106fa again with the Black Kompressor Pad.
