True or False: Dragging the nozzle during the fillet application can result in air entrapment and undetected voids in the seal.

The statement regarding dragging the nozzle during the fillet application being able to result in air entrapment and undetected voids in the seal is indeed true. When applying sealant, maintaining a controlled and consistent application technique is crucial to ensure a proper bond. Dragging the nozzle can lead to the introduction of air into the sealant material, which can create bubbles or voids within the fillet. These voids can compromise the integrity of the seal, leading to potential failures in the sealing capability.

Furthermore, a well-applied sealant should completely fill the intended joint without any inclusions of air, as these voids can weaken the mechanical properties of the seal. By dragging the nozzle, the proper flow and displacement of material can be disrupted, further increasing the likelihood of trapping air within the sealant. Therefore, maintaining the correct technique during application is essential for ensuring a reliable and effective seal, emphasizing the importance of avoiding practices that can introduce air entrapment.
