I'm looking for advice on how to make a car body look used. I'm not looking for "rusty and crusty". I want it to look like a 5-6 year old car where the paint's a little faded and it hasn't been washed in a while. I've started by rubbing out the paint to a sort of semi-gloss level (3600 grit paper and a white abrasive pad). That looks pretty good, but I'd like to add some dust, and smears from rain. Maybe dirty up the windows a bit too. I'm thinking of using the dull side of aluminum foil instead of BMF for the trim. Any suggestions? Edit: I should add that I want the car to look like it is driven daily, not sitting and collecting dust, leaves, etc.
