can you feel it with your fingernail? If so, than it can't be buffed out.
I just went through something like this. It's about 600 bucks to fix or so.
You can use a fine tipped sharpie, touchup paint and a toothpick to fill it in if you want a quick fix, Otherwise I would suggest G&M autobody in san bruno (right off the freeway about 3 blocks on San Bruno Ave).
Gil is the manager and will take care of you.
If you need more info, feel free to contact me on aim/pm.
