[Cool Hand Lurker]

I make a temporary booth inside the shop with cheap plastic sheets. Put some long hooks in the ceiling, hook the sheets to them so you have an air gap up by the ceiling. Make a wide three-sided box from cardboard or cheap panel, put some furnace filters or quilting on the open side to trap the overspray and install an exhaust fan on the opposite side. Put the box on the floor at the exhaust side of the booth. The fresh air will come in over the top of the plastic sheets and carry the overspray out the exhaust side.
