Does it behave like Klasse and Zaino in that a detergent like Dawn will not wash it off? I ask this question because I have #20 on the hood, roof and trunk to test it out, and now I like it. But I have Carnuba on the rest of the car and would like to apply #20 all around. So if Dawn wash, do I have to do the who car over?
 
Won't take all the #20 off, but it will shorten its life. I would simply dawn wash the entire car, clay if appropriate (this is very much recommended!), and apply #20 to the entire vehicle. It won't take that much more effort and you know the job was done right.
 
Cybercowboy is correct. Dawn should remove the carnauba layers and weaken the #20 a bit. A good idea would to use a Dawn wash on the car and then use #20 all over your car again. Laters
 
Don2000g & Cybercowboy are both correct. Dawn will weaken the No. 20, but not eliminate it entirely. Wash the whole car, and then reapply the No. 20. You may even want to give it two coats, depending on how harsh the winter is in your neck of the woods.
