Benefits of Painting Bottom of Aluminum Boat
Aluminum that is exposed to air will oxidize, thus creating a protective coating. This is why few aluminum boats have visible paint. Below the surface is a different story.
Aluminum boats are painted below the water line for several reasons. First off, the paint slows down fouling and chemical corrosion. Second, for avid fishermen, a camouflage paint design gets rid of the tell-tale sign of aluminum which would otherwise dissuade prey. While out purchasing paint, don’t forget to pick up boat motor oil.
