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.
