Dry Ice Could Save Your Car. Here’s How – SlashGear

One incredibly useful feature of dry ice lies in its ability to transform the temperature of affected material in rapid order. Changing the temperature of a piece of metal or some other material can often result in dramatic warping of the material’s face. If dry ice is applied to a surface that has been crushed, it can often result in a reversal of the deformation. This is why car owners have been using dry ice to remove minor dents and dings in the bodies of their vehicles for years. Penguin Dry Ice reports that holding dry ice against a minor bend in the body of your car, followed by reheating with sunlight or a hairdryer, can successfully remove the problem. 

When it comes to damage resulting from hailstones, children in the neighborhood, or a minor collision in a parking lot, dry ice provides amazing cost-effectiveness for fixing body damage. Of course, one thing that should be noted is that with this rapid change in temperature and the expansion of material comes the potential for paint damage. Materials Letters notes that dry ice can be used to quickly strip away paint from a surface, and this side effect may impact the car in an unintended way. Therefore, it’s always best to use caution whenever handling dry ice around your car.
