Which of the following is NOT part of the preparation for a pinchweld?

The preparation for a pinchweld is a critical step in ensuring a proper bond between the glass and the vehicle during an installation. The correct answer highlights that using Metamorphic Cleaner is not part of this preparation process.

In the context of pinchweld preparation, the primary goals are to create a clean surface and enhance adhesion. Using Aktivator Pro helps promote the bond between the adhesive and the glass surface, ensuring a secure attachment. Scuffing the area can improve the surface texture, allowing adhesives to embed better during application. Glass Cleaner is typically used to remove any residues on the glass itself, which helps maintain clarity and ensures that no contaminants interfere with installation.

Metamorphic Cleaner, while important in other contexts, is not routinely considered part of the preparation process for a pinchweld, as the focus is on cleaning and treating surfaces in a way that specifically supports the adhesive's performance. Knowing the appropriate cleaning and preparation techniques is vital for a successful installation and long-term durability of the bond.
