It depends on how steady your hands are. You could use a silver Sharpie marker. That's what I used for the silver border around the dash emblem bezel. Another option is to tape off the area and spray the lip.
Spray the SEM Landau black first. Then, mask off the area. Don't worry about getting the tape right up to the edge when you mask. Leave it long. Once it's all taped up, use a NEW razor blade and trim the tape off flush with the edge. Use a couple light coats of paint so it doesn't bleed through the tape. You could probably use a chrome spray paint. Since it's such a small area, it will still look decent.
