Why should you paint your boat’s engine?
In addition to their aesthetic appeal, engine paints protect the metal surfaces of engines against rust and corrosion. A side benefit of painting your boat’s engine is that the smooth surface that the paint creates can make the engine easier to clean. Finally, depending on the color you select, oil leaks will “stick out like a sore thumb,” which can alert you to corrective maintenance that you need to perform. Offered in aerosol cans for easy application, engine paints are formulated to resist gasoline and oil and the heat generated at an engine’s surface.
Like any painting project, painting your boat’s engine should start with surface preparation, which includes degreasing engine surfaces and the removal of rust and scale. Next, you should prime the surface. In addition to protecting engine surfaces against rust and corrosion, the primer will improve the adhesion of the topcoat, many of which are offered in OEM colors to match the original color of the engine. Uses for marine engine paint include inboard, outboard, stern drive and lower unit applications.
