So I backed into a security gate at my house....

I put a long vertical indent into my rear bumper cladding,
About 10 inches long just to the right of the reflector on the passenger side and in the most "bulbous" part of the bumper.

So two questions ...One has anyone ever pounded out big cladding dings?
I was thinking to remove the bumper cladding and try to stand on the crease till it pops out. I took my tail light off and got my hand in there but could not budge it, But I think with a little more leverage and force it might.

Second...If that is my best course of action, are there any tips to removing the bumper cladding that are worth knowing? I took all the screws out the top and it barely moved, I am aware their are screws on the bottom but it got dark on me and I stopped removing screws.

My third option is a bumper replacement but if the cladding can be pounded out and it looks semi okay I can live with that..
