An insurance policy? Looks like it is scratched down to the primer or bare metal, so it will need paint to completely cover/hide it. I'd start out with Meguiars Scratch-X 2.0 for starters, should make it look a little better. If you can't cover it with paint right away, put some wax over the area to keep any rust from forming in case it went down to bare metal.

To get paint on it, I would use touch-up paint, and ideally dilute it, then use a really fine tip artist's paint brush to fill the scratch, using multiple thin coats instead of one or two thick coats. If you did wax over the scratch before painting it, remove the wax with Dawn dish soap.

There might be better ways to do it, but this is what I would personally do (and have done in the past) for similar scratches.
