What materials are needed when preparing a pinchweld with less than 24 square inches of rust?

When preparing a pinchweld that has less than 24 square inches of rust, using Metal Prep and wiping with water is essential for effective surface preparation. Metal Prep serves to clean the metal surfaces, removing rust, corrosion, and contaminants that could compromise the adhesive bond when installing a new piece of glass. This step is crucial to ensure that the new adhesive properly adheres to the pinchweld, promoting a secure fit and longevity of the installation.

Wiping with water after applying Metal Prep helps to rinse away any residues and ensures that the surface is clean and ready for further treatment or adhesive application. This method emphasizes the importance of addressing corrosion thoroughly to maintain the structural integrity of the vehicle and ensure the safety of the installation.

The options that suggest glass cleaner or scuffing do not adequately address rust removal or surface preparation, which is why they are less suitable in this scenario. Metal Prep specifically targets the needs of rusted surfaces, making it the appropriate choice for this type of preparation task.
