Any secrets?

Hi All, I recently bought an auction car that has a rear bumper pushed in a little from the car behind it parked to closely. It's not scratched but it doesn't want to flex back into it's original position. I know the material is pretty thin but I wasn't sure if anyone had run into this and tried heating or something. Any thoughts appreciated. Thank you

Check w/Ford Dealer or a body shop before heating things up back there!!
You may have "impact reducing bumpers" which are basically shock aborber type mounts. You might be able to pull them back to stock position if they are compressed. (Then of course, you could heat them and launch that bumper to the next county!! JUST KIDDING DUDE!)
