To lighten a metallic color, what adjustment should be made to air pressure?

• A. decrease air pressure
• B. increase air pressure
• C. adjust nozzle size
• D. use different reducer

Answer: (B)

Higher air pressure makes the spray atomize into finer droplets, which helps the metallic flakes distribute more evenly across the surface. That even dispersion reflects light more uniformly, making the metallic color appear lighter or brighter. If you lower the pressure, droplets are coarser and flakes can clump or lay down unevenly, leading to a duller or darker look. While nozzle size or reducer can change spray characteristics, the most direct way to lighten a metallic finish in this context is increasing air pressure to improve atomization and coverage.
