Can I paint over old paint on an aluminum boat?
Just like painting fiberglass or wood, painting an aluminum boat begins with sanding away old paint and oxidation until you’re left with clean, shiny metal. This usually requires 80 or 100 grit sandpaper, which will leave behind some scuff marks. Don’t worry – this is a good thing.
What paint will stick to aluminum?
Latex or acrylic paints are the best for painting aluminum. Choose the ones designed for use on metal. If you’re handling an outdoor project like patio furniture, ensure the paint is exterior grade. Tempting as it might be, don’t go for high-gloss paints because they will highlight imperfections on the surface.
What is the best way to paint an aluminum boat?
Apply a self-etching, oil-based primer that sticks to aluminum surfaces[vi]. Using a brush or a sprayer, apply a thin layer of primer inside the boat. Let it dry and then paint the outside. Let the primer dry overnight, or at least 12 hours, before moving on to the painting process.
