In the context of applying primer, what does the term "fantail artist brush" refer to?

The term "fantail artist brush" refers specifically to a type of brush that is ideal for small repairs, particularly when applying primer in tight or intricate areas on aircraft surfaces. These brushes are designed with a unique shape that allows for precision application, making them suitable for detailed work where larger brushes may not be effective.

Using a fantail artist brush enables technicians to control the flow of primer, ensuring uniform coverage and reducing the risk of overspray or drips that can compromise the low observable characteristics of the aircraft. This capability is particularly important in maintenance tasks where detail and accuracy are critical for maintaining the structural integrity and stealth features of low observable aircraft.

Understanding the function of the fantail artist brush helps maintenance personnel select the appropriate tools for their tasks, ultimately enhancing the quality and effectiveness of their work.
