dust nibs
This is funny. I was just talking to a friend this weekend about what a pain dust can be.
I too paint in a garage and very rarely do I set up the night before, but when I do, dust is significantly reduced. If the night before you sweep, vac and generally clean, I think this helps. The problem is I don't usually want to do this just to spray a few parts. I think it would also help if I constructed a paint booth like Tod's. Perhaps over the winter I will tackle that.
Of course preparation must include clean paint equipment, clean paint surfaces and clean paint!
