Ensure you cover all parts of the railing, including flat sections and intricate details.

   Pour an oil-based metal primer, specifically designed for rust prevention, into a paint tray. Apply a light, even coat of primer to all surfaces of the railing. Use a mini roller for broad, accessible areas, ensuring smooth and consistent coverage. For tight spots, intricate details, or areas difficult to reach with the roller, use a paintbrush to apply the primer carefully.
