Ya, overspray sucks! I made a complete enclosure out of plastic, put a couple of box fans on the garage floor facing out with filters, then put a dozen or so furnace filters in the plastic sheeting so the fresh air could get in. I don`t recommend it (someone on here will blame me for blowin up thier house or passing out and brain damaged) but I got away with it (your wife may not like the way you smell when you get into bed but mine got over it). I picked my days when there was very little breeze outside to minimize dust and lightly watered the floor. It would be harder to paint the entire car at once, I painted the doors , fenders , ect off the car then painted the rest of the car. I know, it`s not the way the pros do it, but i`m no pro either.
