When building your paint booth you can build it using thin ply or plastic sheets from s plastic supply. Build with hinges to make it folding for storing when not in use if in the garage get a fart fan install in wall or ceiling build a air box and install hose fitting six inch vent out make a hose fitting at the top or back this way you can evacuate any overspray and dust. I think they make quick snap attachments for the vent duct these days and the aluminum ducting is flexible and durable though the plastic is cheap.
