Why is tapping the adhesive bead important during installation?

Tapping the adhesive bead during installation is crucial because it helps ensure that the glass is properly seated against the adhesive. This action promotes adequate contact between the two surfaces, which is essential for developing a strong, reliable bond. By tapping the bead, you can eliminate any air pockets that may form beneath the glass. These air pockets can compromise the seal, potentially leading to leaks or reduced structural integrity of the installation. Proper seating achieved through this technique makes for a more efficient and long-lasting installation, ensuring that the windshield or glass maintains its function effectively.
