What follows cleaning an aluminum pinchweld with glass cleaner?

Cleaning an aluminum pinchweld with glass cleaner is an important preparatory step before any further actions. The next step after cleaning is scuffing the surface. This is crucial because scuffing creates micro-abrasions on the surface that enhance the adhesion of primer, adhesive, or paint that may follow. It helps to remove any remaining contaminants and allows for better bonding by increasing the surface area for adhesion. Without this step, the effectiveness of any subsequent application could be compromised, leading to potential failures in the installation process.

While applying primer, drying with air, or painting are all vital steps in the overall process, scuffing comes directly after cleaning to ensure optimal surface preparation before any additional materials are applied.
