[xx(] I tried and I tried to keep this from happening.

Its on the passenger side front fender.
On my way home from work on the highway, a small piece of gravel fell off a truck, I watched as it come closer, bouncing a couple of times I tried to slow down enough to let it go to one side or another, to no avail.
It was almost as in slow motion, for a moment I was sure it was going to bounce in front of me and go under the cruiser...no such luck.
Gary what would be the best way to repair this?
