use zinc anode on boat trailer
I live 400 miles away from salt water. Boat trailers are usually painted steel, and not galvanized, where I live, North Alabama.
Painted steel rusts even thought I live far from salt water.
? If I attached a zinc anode to my trailer, would it reduce corrosion ?
? Does the zinc anode only work if the trailer is in the water ?
Zinc anodes are magic to me.
