That's what the White Diamond does mate. It has a tiny amount of cut in it, and definitely cleans the paint and gives it the finish you see. Awesome product for lighter colour cars.
As for the wax, I put a proper permanent one on with the Collinite, so the finish with the P21S on top is amazing. When the sun goes out, I'll show you some White Diamond'd 'flake pop'!
Oh, my bad When I saw it was a glaze in your original post I assumed it wasnt a cleanser. Seems it doesnt both, might give it a go as I need some more paint cleanser
