I have made a painting cabinet that has a fan in the bottom and several different doors to suck outside exhaust or close those doors and open the front two double doors and lay your parts inside on the open metal grate and turn on the fan and paint to your hearts content without any overspray leaving the cabinet! You can put this unit in a showroom and spray parts and not get any overspray on anything! If you are a shop and you have a sandblaster then you will love having this cabinet sitting next to your blaster!
