Yes, TotalBoat TotalProtect can be applied directly to properly prepared bronze.
Remove any potential grease, oil, moisture, wax, or other surface contaminants from the bronze. Sand or grind the metal until it is bare and shiny. Remove all sanding residue. Wipe the bare metal surface clean with a clean, cotton rag dampened with an appropriate surface preparation solvent specified in the TotalProtect Technical Data Sheet. Apply TotalProtect as soon as the surface preparation solvent has completely evaporated.
