Which of the following is NOT a common method of applying aircraft finishes?

• A. Dipping
• B. Brushing
• C. Spraying
• D. Rolling

Answer: (D)

The method of rolling is not commonly used for applying aircraft finishes, primarily due to the specific requirements and characteristics of aircraft coatings. Aircraft finishes are designed to provide protection from environmental factors and maintain aerodynamic efficiency, which requires a smooth and even application. Dipping, brushing, and spraying are more prevalent because they allow for precise control over the coating application. Spraying is particularly favored in the aviation industry, as it creates a fine mist that can cover large areas evenly and minimizes the risk of runs or uneven texture. Brushing can be useful in touch-up applications and for small areas. In contrast, rolling may introduce bubbles and uneven thickness, which can negatively affect the performance and appearance of the finish. Therefore, the selection of application method is critical to ensuring a high-quality, durable finish that meets the aviation industry's standards.
