Thanks for the input guys. I've got to finish a 76 chevy I have to drive this winter and I'm leaning towards painting it instead of just giving it a semi flat paint job. So this led me to start thinking of what to get and prepare for it. Now I have a garage, I'll make a temporary paint booth. In the past I have just swept the walls, ceiling, floor, and put water on the floor. I'd put a box fan in my one window with furnace filters, and on the opposite side had furnace filters in the walk through door. The problem with that is, you'll never get that building perfectly clean, and you can't go out because of the furnace filters. I should have put them on a screen door. Haha Thanks for your input and help guys!
