Unhappy Removing dents in plastic bumper, possible?

So I came out to go to work the other day, and some moron left me a little present on my rear bumper. Looks like they just barely backed into me because there's no stratch, but the plastic undernear the license plate has a dent that can only really be seen in the light.

Has anyone tried to have dents removed on our bumpers? Bums me out, I was gonna slap on a HFP kit but now this just makes me have to spend more money for someone elses ignorance.

you can try to remove the bumper and use a heat gun on the dent from the back of it and try to push it out. just dont heat too much or you will roast your paint.

as long as the dent is not too bad (bigger than a softball) it can be repaired-shops will heat area-plastic will actually want to get back into the shape it was molded to be

I'm having that done to my front bumper. Same thing, some moron in the parking lot ran a shopping cart into my front right corner. I know a body shop owner pretty well and he said the same thing. Remove it and use a heat gun on the back. I would just try increasing levels of heat until it bends back into place. That should keep the paint from frying.

This type of Plastic used in these Bumpers are designed to regain its shape (Shape Memory) How ever if you don't know what your doing you can toast your bumper faster than you can save it in the process.

Good luck, give it a few days in the heat it'll prob pop out more than what it is now.

a heat gun - just be sure that you don't burn it.. when its hot try using a screwdriver handle or a hammer handle to push it back out... or you can also pour cool water on it to get it to shrinkback in a little while you are pushing from the back with a screwdriver.. good luck and hope your honda bumper would be fixed..

I had something like that on my wifes Tacoma. It was a dent about the size of a golf ball. After a day and a half of being out in the sun it just popped out on it's own.

I used to do this in the bodyshop, take the bumper off and use a heat gun to apply heat to the edges of the dent. Have a bucket of water with a rag and just keep wiping the area as you heat it. Just go slow and be careful not to burn the paint. Once you think you've heated it enough, you should be able to pop it right out. It may not look perfect but it will look alot better than a dent.

tools.

Paintless Dent Removal.

This is NOT done on plastic bumpers.

Be carefull on how hot you get it.

Thanks man, I might use boiling water to be safe like I read in the thread. I will try to use a hammer handle or screw driver handle to push it out.

Thanks man. I am going to try this. I just don't know if can access the inside of the bumper on the car. The dent is around the side on the rear edge of the car.

Update: I got it done! Thanks to you all for the help. I used my heat gun that I have, which worked great. I was careful and I dropped the bumper down to work on the inside part with the heat gun. I then used the back side of a hammer and knocked out the big dent. I had to go to Autozone to get a 5 MM Hex piece to fit to take off the rear bumper and then it was easy. I saved about $100.00 - thanks to you all. This was on a 08 Honda Fit Sport not my Si.
