I will just chime in here and say go for it. I made a paint booth out of thick mil plastic sheeting and an attic fan. I opened my rollup door with a 2 ft piece of waferboard and installed a 1500 cfm attic fan in the board. I then cut a hole and installed an AC filter in the plastic sheeting on the opposite side. Made a nice down draft homemade booth. I did the S-10 in my album in the homemade booth. It might not win any awards, but it came out really good. NO BUGS! Only a couple tiny nibs that sanded out.
