In the partial cutout windshield replacement method, what serves as the base for the new adhesive?

In the partial cutout windshield replacement method, the old adhesive serves as the base for the new adhesive. This approach involves removing the damaged or faulty windshield while leaving part of the existing adhesive intact on the vehicle's frame. The remaining adhesive provides a suitable surface for the new adhesive application, ensuring a bond between the new windshield and the vehicle that meets structural integrity and safety standards.

Utilizing the old adhesive allows for a more efficient installation process, as it creates a seamless connection between the new glass and the remaining elements. It is crucial that the existing adhesive is clean and properly prepared to ensure optimal adhesion of the new windshield.

The other options do not serve as the base for the adhesive in this method. The new glass itself cannot act as a bonding surface, as it needs the adhesive to secure it to the frame. The windshield frame provides the structural support but does not serve as the adhesive's base unless it is in a condition to receive new adhesive directly. The rubber gasket is primarily used for sealing and preventing leaks rather than serving as an adhesive base. Therefore, the correct answer is the old adhesive, as it is essential to maintaining the integrity of the new installation.
