What is the best paint for an aluminum boat?

The best paint for an aluminum hull boat is one that adheres tenaciously to the aluminum, while providing friction reduction for increased speed and lower fuel consumption. I encourage boat owners to apply a primer coat for increased durability and for a strong chemical bond with the aluminum substrate. A friction reducing, low drag, hydrophobic topcoat is ideal for most aluminum hulled boats.

In my experience, the best primer and topcoat for aluminum hulled boats are manufactured by Wearlon, a company out of NY. Easy to apply and touch up, with low VOC and a water based formulation so there are no worries about cuprous oxide and the EPA. Your marina will get off your back while applying these products, because there is no risk of water quality issues. Wearlon products can be found at the link below.
