The most important aspect of a topside paint used to paint an aluminum hull is finding a paint that will form a great bond to the aluminum, with excellent corrosion resistance to protect the aluminum. Paints without corrosion resistance can allow the aluminum to oxidize and pit, which will reject the paint. A couple of the most common paints for this application include TotalBoat Aluminum Boat Paint and Sea Hawk Aluma Hawk. Both of these paints have a dull finish and are available in a variety of colors.
