If you take it to a glass shop they can fill teh chip with the repair kit for about $20-$30, but thats as good as you're gonna get. The sooner you go, the better it will fill in and conceal it. I've seen some fixed to the piont that you REALLY have to look hard to see where it was, and some that you can't even tell were ever fixed.
When a rock hits the glass, it creates a cavity inside the glass, kind of like an air pocket. The stuff they use to fix it fills in the cavity so water & other stuff doesn't get in there.
