Not sure if a mini gun would help all that much. Lack of consistent air is difficult to work around for consistent paint work. Air pressure can affect how the color lays on the panels so painting different panels on different days under different conditions at different pressures can create some color variance depending on the colors used. Little compressors tend to work really hard to keep up so you end up with heated air that's loaded with moisture, also a big problem with paint materials.
