Gloss black shouldn't be too hard. I'd get a little bottle of model paint from the hobby store or try to find matching fingernail polish (without the sparkles) from Walgreens or someplace like that.
Be aware that there's "perfect match" and there's "not exactly". "Not exactly" looks like crap because it draws your eye to the blemish. Clear beats "not exactly".
