The reasons you have selected a duplex stainless include its resistance to atmospheric corrosion and its resistance to stress corrosion cracking.

What situation has arisen that defeats these properties of duplex stainless?

I would recommend a vapor corrosion inhibitor (VCIs) wax based coating. The wax base coating provides VCIs that will stop the corrosion and UV protection to extend the life of the coating.
