I was dusting my car the other day and noticed a dent on my rear bumper. It's up and down on the upper curved part of the bumper about 1 inch long and varies from 0.1 to 0.2 inch wide. And the paint is still intact and shiny. My guess was some bastard hit it with a shopping cart or something... I might also add that it's about .1 inch deep...

Anyways, what's the best way to fix it short of going for a complete repaint?
