These shots show what a truly miserable workspace I have; substandard lighting, inadequate space, and working with whatever junk I can fish from the trash can, my specialty by default. The filter-wall was made from office building HVAC filters, goose tape, and cardboard. I spent 3 years fishing out the premium filters from the more dirty ones, and you can see that I had to settle for what I could get; thus, the darker/dirtier filters. I knew it would slow down a high volume of trash, but I had no idea that it would work so well because I had zero trash in the paint. Also, notice the high tech air hose plumbing. By the time I got to final paint, I had learned that it would be impossible to manipulate a hose around the car, so I had a hose on each side and swapped air hoses when I went from side to side.
