This guy doesnt know squat about a paint booth. He is building a clean room. A booth is negatived pressure, sucks fumes out, a positive pressure is like a balloon, blows it out every crack... There is a fundamental principle in ventilation and he missed it in class that day. Sucks fumes out of building NOT blowing them everywhere.
Shame it has been viewed a million ties, none of those people learned anything cept to glue some plastic up. I will figure out how to post something I have saved.. The finishing academy tutorial was so good they must have removed it due to the fact it was complete enuf a guy didnt need the school after reading it.
