Laptop surface deep scratch

I know this may not be the best place to post but you guys always seem to give me the best answers. My sister got a pretty deep scratch on the surface of my laptop it is a gloss black top. I keep this thing in prestine condition and it gets me angry when stuff like this happens. Any body know the best product/way to remove this? I tried all my household things and nothing seems to be filling it up. A silicone based products I hear usually work the best. Laptop is in sig if you're wondering.
