The hood made through model year 2007 is a composite. No rust, no risk of hail damage.
Sorry, I had to rub it in. There are so many improvements made since 2007, I had to mention the rare few things that were better back then.

There are paintless dent removal services that can remove hail damage and other dents, done at your house. I actually have a guy coming to our house tomorrow to remove dimples, door dings, shopping carts creases and such from a 2007 Saturn Sky that I am restoring. The process is using bent rods of various shapes, skillfully pushing the metal from behind. I have used him in the past on a Pontiac Solstice a few years ago. He does his magic. The distortions are gone. It is best to polish the car, mark each perfection with painter's tape, and then have the work done. They work off the reflection to get perfection, hence the need to polish the car.
