For signing glossy surfaces, I would recommend a Sharpie. You can get them in a few different colors. In fact, I just bought a silver metallic; though haven't tried it yet. Plus, you can get them in broad, medium or fine point. For signatures, try the fine point. Get one and try it out - they're not expensive.
