When I worked at a grocery store we'd throw them out the dock door. It was lots of fun until the manager caught on...I never even thought of getting the dent nice and toasty from a heat gun before using the dry ice. project!
Something else that gets VERY cold is compressed CO2. Id be willing to bet that would get plenty cold if a 20 OZ tank were emptied on the panel.
The canisters that of compressed air that are used to clean off keyboards are compressed C02. Hold them upside down and that's what comes out...super cold.

I was thinking much larger. I fill CO2 at Scheels and when You dump a really full bottle the cans get extremely cold. You can't even touch them or you'll get frost bite... so I bet if you could figure out a way to unleash an full tank onto the heated dent you'd get some pretty extreme temp changes which is what you want.
