Living within 500', not elevation, of the ocean everything rusts. Give it a chance even plastic will rust.
Salt air is tough on everthing & if you get a storm where the spray from the waves becomes a fine mist getting blown inland you need to get far inland to get away from it. Oceanside CGs are nice but they are even better when the wind is blowing offshore.
Rust & corrosion is why all fasteners on boats, worth buying, are made of stainless steel. Saltwater boat owners are forever washing their boats. The salt gets everywhere.
