I am trying to keep low expectations on the sanding, because to be perfectly honest, the filed finish does not look all that bad - bare aluminum has a lot of shock value judging by the reactions of my friends and family that have seen the car.
Tom Kirkham told me to sand with 120 grit (3M "Stickit") automotive sandpaper with Dawn dish detergent. It basically eliminates the dust, but I am using a respirator to be on the safe side.
Eventually, I may paint the car anyways. (I want to paint is like a '64 daytona coupe - viking blue with thin twin white stripes and the big meatballs, etc.)
It should be an adventure sanding it nonetheless.

Brent - I think your stripes look good in the pictures - your are probably being overcritical.
