I thought about that and I just cant see blowing a fan right on my work...even though it might keep dust out better. The space is about 16x13x8...and based on the CFM rating of the fan on max it exchanges all the air like 5x a min but there is no breeze or anything. I have a 4x8 intake filter using tacky 20x20 paint booth filters. Maybe I will just try to turn it down a little and make sure it is sealed better. I do have 2x2's and 2x4's supporting everything for the most part..it is pretty rigid though.

I think the big thing is I didn't wet the floor....we will see what round 2 brings tomorrow...
