paint booth

ok well today i got 3 home depot fans and 4 filters.
i have never heard of a paint diffuser so it scares me and i dont like it haha,
but yah all and all i figured two sucking in and one blowing out... get the one going out wet before i start painting and that way the moister and filter catch most the paint and have it pull through... it wont be a electric free paint booth because its a garage and it for a few hours of painting at the most in a house im renting haha so if something like this would work and be alrite im ok with it. most everything i do at work everyday is dangourous (oilfield) so whats a little more at home.. in my race car no less8)
Ya but i mite maul things overnight
