I washed my car today and laid down a good coat of Meguiars Gold Class to seal things up and put something on the car (I had taken off most of the old wax beforehand). When I finished with that, it was really too dark to do another coat (I am plannign on throwing on some S100). Can I just use a california car duster to get off any dust that may have settled overnight and go to town tomorrow with the S100 or do I have ot wash it again to make sure it's clean? (note: the car is garaged) Thanks!!
