Sure looks like your doing OK ! When Redline painted their Chally he literally built a wooden frame covered in clear plastic to help with light. He then also installed a couple box fans with furance filters, drawing and discharging ventilation. Also watered down the floor too I beleive. I'm sure the descrption and pics have long been deleted by now of his "McGiver" paint booth, the results were great.
Hey Chris, if you see this thread give our friend the "building rights" for the garage paint booth.
