What's the best way to protect cast iron outdoor planters during paint?

To protect cast iron outdoor planters during paint, follow these steps for optimal results:

1. Clean Thoroughly: Remove dirt, rust, and old paint using a wire brush or sandpaper. A clean surface ensures better paint adhesion.

2. Apply Rust Inhibitor: Use a rust converter or primer to prevent future corrosion. This step is crucial for longevity.

3. Choose the Right Paint: Opt for high-quality, weather-resistant enamel or spray paint designed for metal surfaces.

4. Apply Multiple Coats: Two to three thin coats provide even coverage and better protection against moisture.

5. Seal with a Clear Coat: A clear protective sealant adds an extra layer of defense against harsh weather.

By following these steps, your cast iron planters will stay vibrant and rust-free for years.
