Painting Aluminum Hulls

Why Paint an Aluminum Boat?

Painting your aluminum boat does more than just enhance its appearance—it protects against corrosion, makes cleaning easier, and can dramatically extend its lifespan. Many Lund boats come with durable factory finishes, but years of wear or changing aesthetics often lead owners to repaint. Preparation is the most important factor for achieving a smooth, long-lasting finish.

How Does Someone Prep and Paint Aluminum?

• Deoxidize: Start by thoroughly cleaning and deoxidizing the hull with a product specifically formulated for aluminum surfaces. This step removes grime, rust, and old oxidation layers.
• Sand Lightly: Use fine-grit sandpaper to roughen the surface, ensuring the primer adheres properly.
• Apply Self-Etching Primer: Use a primer designed for aluminum to create a strong bond between the metal and the paint.
• Paint in Thin Coats: Choose marine-grade paint compatible with metal surfaces. Apply multiple thin coats, allowing sufficient drying time between layers to avoid drips or uneven patches.
• Seal for Extra Protection: Optionally, finish with a clear UV-protective coat to preserve the color and prevent fading over time.

Eye-Catching Transformation

Scenario: A fisherman gave his scratched and weathered aluminum hull a complete makeover. After meticulous etching and priming, he applied deep blue marine-grade paint in thin layers. The final clear coat added a sleek shine, turning heads at the dock. His project brought new life to an old vessel—at a fraction of the cost of buying new.
