Topic: Rusting spots occur on electroplated lacquered surface after few days.

I am facing a problem that after electroplating CRC pipes
i.e electroplated brass and nickel, I lacquer them but after few days rusting
spots occur. Pictures attached with this message sent by my customers.

During my process, we pretreated items properly and after
plating we wash it with sodium dicrobate and after drying properly, we lacquered
it. But after few days or after month, rusted spots occur.

Plz guide me, I will be very much thankful for it.
