Before applying POR-15, it's a good practice to lightly sand the surface to create a mechanical bond that will enhance adhesion. Use a fine-grit sandpaper (around 320 grit) and sand the surface in a circular motion, taking care not to apply too much pressure and create deep scratches. After sanding, wipe the surface clean with a tack cloth to remove any dust or debris.
Finally, apply a metal primer designed for use with POR-15 to further improve adhesion and provide a smooth base for the paint. Follow the primer manufacturer's instructions for application and drying times. Once the primer is dry, the surface is ready for the application of POR-15, which should be done in a well-ventilated area using proper protective equipment, such as gloves, goggles, and a respirator.
