I make QD out of rinseless wash and mix in about 2 oz of KSG into the gallon I make. Although I don't have Klasse on the car currently I have and currently do use this mix for QD use w/o a problem at all.
As far as smidging goes, well it could be applied to thickly, so because of this I must ask you Bicycle, how are you applying KSG to your car? I'm glad you waited 12 hrs inbbetween applications, this is crutial to success w/ Klasse.

BTW, you can never have too much Klasse!
