That dent doesn't look that bad. I'd leave it alone. My truck is a warrior, it has been in service since it was born in 1965. It's life is more leisurely now, but it still works. It has been a contractor's truck, a trucker's truck, and now my truck. It has all the scars from it's lifetime of working, and with a coat of wax, it shines really nice. If you saw my tailgate, you'd run away. it has seen better days, but still looks good. If I were to bring the truck back to factory-fresh condition, then all the dents would have to be fixed. I like the used look much better.
