You could do a potentially decent job just by laying plastic sheeting on the floor and forming sides to protect shop equipment. I've done that and used box fans with filters to pressurize the space to push fumes out the far end. I did that in summer, so I set the windows/doors up based on prevailing winds, which helped. Once I was ready to shoot, I sprayed the plastic on the floor real good with water to catch anything and off I went. Paint is still on the car, so wasn't a total fail LOL.
