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

Are the letters grooved into the front of the unit?

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.

If it is a water based paint you could also quickly wipe off any that strayed outside of the trough.

Or, and I know this is going to sound weird, but find a guy who collects and paints miniature soldiers. I have a friend who does this and what he can do with a paint brush is unbelievable.
