Will heating it up with a cig lighter flame be enough? I just took the bumper off earlier before I post this thread and the plastic (or rubber?) is pretty thick... I mean you can't see where it is dented from the inside the bumper... I also notice that the body shop that did the the repair on the bent bumper a few years back from someone rear ending me didn't put some screws back; the bottom four screws of the rear bumper to be exact. Don't really need it, but it still pisses me off...
