Thanks for the reply, Cartman. No, the cruiser actually did it when I first got it. I thought that maybe the surface was rough and that a smooth glass-like finish, like on my 1988 Berretta GTU, would let dust just slide off. Wrong. A towel or a "Hollywood Brush" just sems to slide the dust into a pile, even on the vertical surface, where you think it would just fall off.
I kind of hate the thought of hanging a chain down, like those home fuel oil delivery trucks I use to see when I was kid.
