Hello, Brijesh. When parts are anodized, the anodized film is a honeycomb-like structure whose pores can be filled with dye if desired, or left empty. Then almost boiling hot water, or another sealant, is used to close the pores so that dirt and unwanted discolorations will not be absorbed into them.

By now you can probably foresee that how much sealing is required is proportional to how much anodizing is present, and that different sealants may be required based on what kind of dye was used and what kind of service the parts will see. If you can flesh out your question with more details, the answer may be less vague. Good luck.
