Uhh, Scratches, will it buff out and how?

I hit a metal bar on the freeway yesterday, didn't see it until I ran it over. After a Jan 1, 2005 pickup date, this was the longest I have owned a new car without a single scratch. The streak is now over.

Anyway, there are several scratches, all about 3 inches long, ranging from what look like clearcoat depth to one where the undercoat can be seen, can't tell if it's down to bare metal. They are very narrow, though, like what a knifle blade would do.

Will any/all of this come out/buff out/etc?

What's the best aproach?
Touch up?
Thanks.
