How to refresh brass door sign?

[Thomas_Blekinge]

The door sign is made of brass with an engraved name. The letters were painted black, but the color has faded. What type of paint is suitable for touching it up? Can you paint the entire sign and then wipe off the paint from the rest of the surface?

The door sign is in brass with engraved name. The letters were painted black but the color has faded.

I carelessly fill in the text with black ink on my brass door sign. Wipe off what has gone outside with a dry cloth and polish with copper polish over the entire sign. I fill in every couple of years, polish a few times a year. The door sign was not treated or lacquered from the start.

Sure, you can meticulously fill in with black lacquer, but the black will turn gray in any case after the polishing agent.
