I just use very fine sandpaper. You can now get it up to 10,000 grit! I generally use about 2000 grit. It does not strip the paint off, just sands down the dust.
I use enamel, and the longer drying time invites more dust while it is still wet. I made a heated drying box. Not only does it speed up drying, but I get far less dust than I did previously.
