These two sea buoys have been floating in the Atlantic Ocean, in Noirmoutier, for 4 years. The yellow buoy, a mild steel buoy protected with ZINGA, was compared to the green buoy that was galvanized by the traditional hot-dip process. The two buoys had received the same type of topcoats with the same layer thickness, with a supplementary adhesion coating for the hot-dipped buoy.
