I believe people have said they use Acrylic Spritz (AS) over carnauba, but there is another Sonus product, Carnauba Spritz (CS) which would probably be better suited.
I was wondering about some similiar questions... can the Sonus Acrylic Spritz or Glanz be used over UPP/UPPS? I have some nice, new UPP/UPPS layers on my auto and am interested in an acrylic coating if compatible. So I guess my question would extend to the Werkstatt Jett & Gloss products also?
Acrylic Spritz works well over anything and everything I have tried. I prefer AS over CS although they're both nice. Detailing Spritz works very well, too, but if I had to have one, it would be AS. I am currently maintaining my Pinnacle Sig II with Griot's Speed Shine or Sonus Acrylic Spritz, depending on the mood.
