Also, you don't dust your car in a circular pattern. Only losers do that. Lightly dust each panel using almost no pressure and moving the duster in straight lines.
This is the single best purchase I have ever made vehicle related in my entire lifetime. During spring and summer, I can go for months without washing the car. If I get some bird droppings or if I run through a random puddle or something and get some splashies, I will use Griot's spray-on car wash.
My good friend turned me onto the California Car Duster, and he still uses the same one that he bought back in the early-90s to use on his new VW Corrado. He still uses it, but this time on his F80 M3.
