Dave, if you use a fan like Daryl and myself did you will be fine. Mine is setup in my hobby/computer room at the back of the house, I made a board for the window with a dryer vent. I just tested it using model masters enamel out of a can and it works great no fumes at all, Very happy with it. Thx. for checking it out guys.
Dave here is the Part No. for the fan i used. dayton 1TDR3 , i picked it up from graingers. If you decide to do it and need any help or more pictures or measurements feel free to Pm me.
