Proper surface preparation is critical to achieving a long-lasting finish when you paint metal fence. Using a wire brush effectively removes rust, a common issue affecting metal fences. Applying a quality rust-inhibiting primer provides a protective barrier that prevents future corrosion and ensures the paint adheres well to the metal surface. A professional painter understands that choosing the right tools and materials impacts how long the paint endures.
