Restoring appearance of master cylinder?

I know the right answer is “remove it and either take it apart or buy a new one”. Short of doing that, which I will do one of these years, has anyone tried to restore the appearance of their master cylinder while it’s still in the car, and if so, how did you do it? Were you pleased with the results?

Now that I’ve done a 4bbl upgrade and painted exhaust manifolds, the eyesore in the engine bay is now the master cylinder. The wiper motor isn’t perfect so that’s also on the list but it’s not nearly as bad as the master cylinder.
