Hey that tent idea is great!!
Someone here had told me that I could do the same thing............but to prepare the carport, wet it down from top to bottom (inside), and let all elements settle.
Then take heavy plastic, like you have here, and close off the front of the carport.
I'm thinking I can borrow a few fans from the hospital........the floor typ fans that is used to dry wax and such, and have them facing outwards to blow fumes out. Like this
Ya think that would work?
