I have the paint removed from my front bumper but I have a few gouges and some small dents in the bumber, not all the way through but just enough to be noticeable. Does anyone know what I can use to fill them in with prior to painting, something like a bondo or spot putty glaze perhaps?

I believe 3 M makes a product called Flexible Parts repair. It's a 2 part system that's as pliant as your bumper. It's sandable after it cures.
