Mark Levinson - how to fix white logo paint that has peeled away?

I think that I would try getting some paint that I could thin out enough so that it runs a bit, then set the amp so that the face is horizontal with the ground and dab it in with a something a bit smaller then the groove (pin/needle).

There are paint sticks such as this that are designed specifically for filling in engraved lettering or lines.

Levinson used General Motors paint I was once told by one of their company reps.  I don't recall the exact name of the white, but he said that it was the purest white paint that they had found at that time.  Call Levinson and ask!

Yes, if you plan to do it yourself call ML and get the exact paint color. White is very hard to match and even slightly off will look worse than it is now IMO.

What rockness said and use these or similar.
