paint booth

well my garage is a one and a half car garage. 1 space big enough for the car and then a regular door by the garage door to walk in and then the space left over is for walking and washer/dryer and sink.
then at the other end of that is the other door to exit as well.
The only flourecent light strips are right on that border line were i would drape the plastic sheeting.... so im thinking seperate that off and leave the light outside of the room. add a few lights inside. and have the garage door be the intake and the far exit door be were the air escapes.... wet everything down start spraying later at night and all is well??
