We tried to find a shop that would rent out a booth for weekend use but none were available. We were told that whatever we do in the booth, the shop was responsible for and EPA fines are expensive.
The Garage is so jammed with stuff that it was not an option. We did have a large backyard and side access. We purchased a Harbor Freight 14 x 24 foot car canopy on sale for $150 that can be staked down for the wind. It also weighs 130 lbs. We then covered the sides and floor with Visqueen 6 and 8 mill plastic sheeting and duct taped it down to the top. One end was left open for access and to move parts through and closed up with bungee ties around the down tubes.
Two 20-inch provided ventilation box fans PUSHING AIR IN. These fans are not explosion proof and you do not want any VOC going through them.
The exhaust has 6 filters measuring 24x24. The fans will vent out the booth in a few minutes and over spray was not really an issue. There was no over spray anywhere near the exhaust filters on the outside!
There was not too much dust inside. It has plenty of room for parts and the car.
It is not as good as a REAL paint booth. But then again, I am not a REAL painter!
