What is one function of the fairing tool in the sealing process?

The function of the fairing tool in the sealing process is primarily to shape and smooth the sealant applied to parts. This tool allows for an even distribution of sealant, ensuring that the surface is not only aesthetically pleasing but also functional in providing a reliable seal against environmental factors such as moisture, dirt, and air infiltration. Properly shaping and smoothing the sealant is essential, as it helps in achieving the necessary geometrical configuration for effective sealing. A well-applied seal reduces the likelihood of failures and enhances the structural integrity of assembled components, particularly in aerospace applications where precision and reliability are critical.

Other tools or processes like applying heat, mixing sealant, or creating pressure serve different roles that complement the sealing process, but the fairing tool specifically focuses on the final application and finish of the sealant.
