Start by cleaning the entire marine engine thoroughly with KBS Klean. Once clean, treat any rust spots with RustBlast to remove rust and etch the metal for maximum adhesion. After cleaning and treating all rust spots, apply Motor Coater as your finish coat.
💡 Pro Tip
For marine engines prone to rust, consider priming the prepped surface with RustSeal after the RustBlast treatment and before applying Motor Coater. RustSeal permanently stops rust and gives your finish coat a stronger, longer-lasting foundation — especially important in wet marine environments.
Before you begin, review the complete Motor Coater application instructions for full prep, priming, and coat guidance.
