Dear Sarangapani Venugopal,
Better go for Zinc lamilar coating, (that is Zinc + Aluminium ), after this coating for identification , colouring or different color of sealant is also available.
One more possibility PTFE or Xylan type of coating also will help.
For this type of coating, we will avoid the hydrogen embrittlement also.
