What happens in this clip
Once the primer is dry on the metal frame components, apply three coats of a durable topcoat paint. The creator uses Rust-Oleum High Performance Enamel in semi-gloss black. Use a spray shelter to ensure even application and protect from environmental factors. Apply multiple thin coats, ensuring full coverage by spraying from all angles, allowing adequate drying time between each coat according to the manufacturer's instructions. This enamel provides a tough, protective finish suitable for outdoor conditions.
Goal: Apply a durable, protective topcoat to the primed metal frame
What's used

About the full video
This project details the complete restoration of an old park bench, transforming it from a rusty, dilapidated state into a functional and aesthetically pleasing piece. The process involves thoroughly cleaning and repainting the metal frame, cutting and preparing new wooden slats, applying a durable UV-resistant finish to the wood, and finally assembling all the components with stainless steel hardware for longevity.
Step 6 of 9: Apply Finish to Metal Components
Once the primer is completely dry, apply two coats of a durable metal paint (e.g., epoxy enamel or oil-based paint) in your chosen color. Allow adequate drying time between coats as recommended by the manufacturer. For best results, use a high-quality brush or roller, or a spray gun for a smooth finish.
