Are you painting the car in the bay that it is sitting in the pics? if so, what are you doing to keep dirt and dust down when you spray the body. I have a similar garage situation and want to shoot paint on my car, I was thinking of building a plastic tent over the car, but if I can get away with it, I will skip the tent thing.
blow the dirt away with air and sweep wet the floor a couple hours before painting this like a 200 dollar paint job so probably wont be the best
