DIY: Dent repair with Dry Ice

I had heard this urban legend that you can repair door dings and dents by rubbing dry ice over the dent and then heating it with a hair dryer or heat gun. It seemed simple enough, so I decided to try it on the wife's urban assault vehicle which has its fair share of door dings. I went over to our neighborhood grocery store and got 2 pounds of dry ice for $3. Here is the what the test door looked like before the test. Essentially the process is to take some dry ice (while wearing gloves, as i

I tried this on my Cherokee as I had an extra fender. Bought an infared temp thing from Harbor Frieght ($25) and heated up the fender with a heat gun to 350 degrees. I then used the dry ice...no paint damage. But, this was on a Jeep. Good luck

Just some feedback.....

I tried this on my 2001 C2. I loved the pics and the DIY - made me very comfortable trying this.

I used a hairdryer to heat the metal in between dry ice applications, and very honestly I was afraid to get the metal too hot so I may not have gotten the metal hot enough.

The process did not work for me as well as the OP - I feel like it did improve the dings a bit, so I am pleased that I tried it. However, it did not make them completely go away.

I did do repeated applications, so I feel like I did all I could (except getting the metal really, really hot).

Your mileage may vary - bottom line is it improved things but did not completely make them disappear.

Hope this helps.

I found a video on youtube for Prius Bumper repair - if you heat the bumper with hairdryer the plastic softens and it is easy to push the dent out from the inside. No dry ice required. I tried it on a prius (and worked well) - but did not need to try on the 911 yet ....
