Options to fix a visible, deep scratch

I have an Imperial Blue Metalic 335i. Love the color. I noticed recently that the car got scratched somehow and it has 3 scratches about 2 inches long. They're deep enough to expose the underlying metal. Can someone please tell me the best fix for this? The options I can think of are

1) File an insurance claim and just have them deal with it.
2) Use touch up paint myself and try and fix it.

I'd love to get some advice on the best way to fix this.

Thanks,
sb

A surface scratch that will `catch' your fingernail is approximately 0.04 Mil (1.0 µ) deep will usually require wet sanding
