Backyard paint booth

With spring comes pollen and bugs. I saw a bead of sweat drop off a painters chin almost exactly in the center of the roof panel of a 65 Mustang during final coat. :(
I saw a hair fall in wet paint on a Chevelle deck lid too. Painter had just washed out the gun when his girlfriend decides to have a close look. :(
If you want to shoot underside of hood, door jambs, etc.. , where flaws dont matter thats fine.
For the exterior shell painting, rent a proper place if you have to and pray about those accidents that can happen anywhere. Good luck
