With my experience of Klasse, Dawn doesn't affect the layer. I have experienced this with all the cars below, a Lexus LS430 with pearl white-ish paint, and a black '92 BMW 325i. I'm not sure who makes the paint of the cars though...
As someone here said before, modern clearcoats bead, but you can tell the difference of water beading on a Klasse'd surface and a squeaky clean surface.
I would wash your car with Dawn to remove the Collinite, and then maybe with a regular pH balanced car shampoo. Then start with the Blitz.
Good luck and have fun!
