I have a black trans am. You guys know the deal, drive it and it gets dusty. I usually just qd the car after using the cal.duster after the car cools down. I think I have developed a few scratches this way though and I think it happens when I use the z6. Should I not be using it after driving the car and just wait to wash the car and maybe just use the cal. duster? Also, how often do you guys wash your car? I do not drive it everyday so I usually just dust it with the cal. duster and then z6 it, is this ok. btw, I am using zaino
