How many layers of SP-207 are applied to an aluminum pinchweld?

The correct answer involves understanding the standard procedure for applying SP-207 to an aluminum pinchweld during the installation process. For optimal adhesion and to ensure a proper seal, two layers of SP-207 are applied. This technique enhances the bonding strength between the glass and the pinchweld and helps to ensure that the installation adheres properly and maintains structural integrity.

Applying only one layer might not provide sufficient coverage, while more than two layers could lead to complications such as improper curing or excessive thickness, which could affect the fit and seal of the windshield or glass being installed. Thus, the application of two layers is considered the best practice in this scenario.
