6 Best Paints for Aluminum Boats: Reviews and Buying Guide for 2020

Sprucing up your aluminum boat with a fresh coat of paint is a great way of personalizing your boat, but paint is also important for protecting your boat. The right paint can prevent corrosion and UV damage, besides improving the performance of your boat.

If you have a boat with an aluminum hull, it’s important to choose a paint that you can apply over this material. Here are our top picks.

Top Features to Look For When Choosing Paint

The best paint for aluminum boats should be durable and easy to apply. You can shop for paint and primer systems to find complementary products that deliver the best protection possible, or opt for a paint that doubles as a primer to save time.

One of the main issues you can encounter with your boat is to have marine growth on your hull. Algae and other invasive plant species can attach themselves to your boat if it’s still for long periods of time. Species like mussels and barnacles can also grow on your hull and cause damage.

The best paint for aluminum boats should use copper or another ingredient to repeal these invasive species and prevent marine growth. Manufacturers refer to this feature as anti-fouling.

You should also look for a product that is UV-resistant. UV rays can damage your boat’s paint and cause it to peel. If your boat’s paint is peeling, UV rays could damage the hull of your boat.

If you need to paint the inside of your boat, look for a non-skid paint or make sure you can mix a non-skid component into the paint you selected.

Lastly, color selection is an important consideration. Some manufacturers offer classic colors like gray or white, while others have a more original color selection.

Additional Considerations for Painting an Aluminum Boat

You need to prepare the surface before painting it. If there is old paint on your boat, you should use sanding paper to remove it. You might need to use a de-waxing treatment depending on the type of paint you decided to use.

Sanding is an important step because salt and slime can build up on your hull. Paint won’t dry properly if you don’t apply it to a clean surface.

Check the drying time of the paint you selected. Most products have a time window for applying additional coats or for launching your boat.

You will get better results if you apply a primer. A primer will make the paint last longer and help protect the hull.

When painting, remember to use thin layers. You might need to apply more than one coat of paint to get the most coverage possible or make the color look brighter.
