How to Paint the Inside of an Aluminum Boat

Work on a warm, dry day.

Scrub the interior of the aluminum boat with a degreasing agent. Rinse the surface thoroughly using a pressure washer. Allow the aluminum to dry.

Apply a coat of etching primer to the inside of the boat. Wash the brush with water. Allow the etching primer to cure for a full day.

Pour the epoxy resin into the 5-gallon bucket. Stir in the catalyst and continue stirring for no less than five minutes.

Apply the epoxy to the interior of the aluminum boat using the 4-inch latex paintbrush.
