It can be done by a brush plating (anodizing) method, but I could never get a good match and always had a problem with the edge of the tape masking. It is not easy to do and requires a significant amount of experience to do it.
For commercial type work, many companies allow a chem film touch up. Trade names of Iridite and Alodine used to sell touch up kits. Caution -- It is acidic and contains chromic acid.

Not to recommend a sloppy fix or trying to fool the customer, but if this is for interior use on small spots where corrosion isn't much of an issue, and it is not a mil spec type part, and with customer approval, anodizing shops will sometimes simply use a magic marker -- because it's easy, reasonably permanent, and non-hazardous.
