What are the three most common methods of applying paint on aircraft surfaces?

The three most common methods of applying paint on aircraft surfaces are dipping, brushing, and spraying.

Dipping involves immersing the object in a vat of paint, which ensures complete coverage but is not practical for most aircraft applications due to size and surface considerations. Brushing allows for precise application and is useful for touch-ups or small areas. However, it may not provide the even finish desired on larger surfaces.

Spraying is the most widely used method in aircraft painting. It allows for an even application of paint, reducing the risk of drips and runs while covering large areas quickly and efficiently. This method is crucial in achieving a professional finish, which is important for both aesthetic and functional purposes, as paint on an aircraft not only contributes to its appearance but also provides a protective barrier against environmental elements.

The selected answer captures the practical approaches typically used in the industry, reflecting techniques that align well with the requirements of aircraft maintenance and painting standards.
