During the coating process, what is crucial to ensure a smooth finish?

Applying in multiple thin layers is crucial to achieving a smooth finish during the coating process. This technique allows for better control over the application, reducing the likelihood of drips or uneven thickness, which can occur when applying heavy layers all at once. Thin layers dry more evenly and adhere better to the surface, promoting a more uniform appearance. This method also gives the coating time to cure properly between layers, minimizing imperfections and ensuring that each layer bonds effectively with the previous one. Consequently, the final finish is smoother and more visually appealing, which is particularly important in aircraft fabric covering where aesthetics and performance are key.
