Commercial aviation is a highly competitive industry for both the OEM (Original Equipment Manufacturer) and the airlines. The exterior coatings on airplanes are increasingly being used for branding and marketing by the airlines, in addition to the protective function they must provide the airframe from extreme environmental conditions. This paper covers the fundamental environmental and performance requirements of the exterior decorative coating system, the processes and materials used to paint these airplanes, current improvements and future goals. Special emphasis will be given to investigation and solution to the paint adhesion issue known in aerospace as "rivet rash".
