What is the first step in performing the full cut method?

The first step in performing the full cut method is to trim the urethane down to 1-2 millimeters. This initial action is crucial because it allows for the proper handling and removal of the windshield. By trimming the urethane instead of removing it completely or applying adhesive right away, you create a more controlled and clean surface for the subsequent steps in the installation process. This careful approach minimizes the risk of damaging the vehicle’s body or the glass during removal, ensuring that the area is prepared adequately for a new seal, promoting better adhesion when adhesive is eventually applied.

In contrast, removing all urethane right away could lead to complications in the removal process, while measuring existing urethane, although important, is not the immediate first action required in this specific method. Applying adhesive too early would also be inappropriate, as the surface needs to be properly prepared first to ensure optimal bonding.
