Ah! Then maybe either mask and re-paint, or, what might be easier, use painted tape for the frames. Lay down some 'Sellotape'-type clear tape, on a grease-free, smooth surface, and paint it the required colour. When fully dry, cut into strips of the desired width, and lay over the frames, pressing down as you go. Once satisfied, the tape can then be sealed with 'Future', and carefully touched-in with clear matt when dry.
