I was pretty scared of playing with resin in my basement. With casting toys and painting stuff, I had nightmares of these noxious green fumes wafting up throughout the house making everyone sick. But now I don't need to worry. I installed a blower in my work area. It's connected with a straight run of ducting to a dryer vent outside the house. The blower I got moves 265cfm of air so it's pretty beefy. It'll exchange the air in a 1200 cubic foot room in under 5 minutes. Nice! Next I may build a hood out of cardboard to direct the flow but I'll see how it works.
