Galvanizing is a chemical bonding whereas painting is a coating. Painting may need to be repainted over time. Since it is in a wet environment, getting a paint to set up properly with proper coating might be an issue. However, a couple of coats of a two-part epoxy might not be a bad alternative, but again cold be tough to do in that environment.
