To the OP, fyi. I finish with Keramik on the Rupes Mini, MKII’s and Mille and have topped it with WGDGPS 3.0 or Collinite 915 and the results to this day have been nothing short of spectacular on all colours ranging from whites to blacks. I’ve been using CarPro Essence on Rupes yellow pads too after cutting with Zephir and Meguiars maroon thin cutting pads and topping with CQUARTZ with phenomenal results. Dont be afraid to mix and match or venture out, I assure you, you will fall inlove with your Rupes stuff even more as they really do play well with other brands.
