How to read an airbrush pattern
Before spraying your project, practice on cardboard to adjust the finish viscosity and airbrush settings. If you're using an air compressor, set the pressure reaching the nozzle to 25-30 pounds per square inch (psi). Spray a short burst of finish, and then adjust the fluid flow using your results against the examples shown in the chart right. Airbrushes produce a conical spray pattern that can be narrowed by holding the airbrush closer to your work and reducing the fluid flow.
