<h4 class="dechead">On One Hand: It Does Work
Dry ice causes hail dents, which are usually small, to pop back out. The dry ice makes the metal contract, which causes the dent to remove itself.
On the Other: There Are Necessary Conditions
Dry ice dent removal only works on small dents, and it works best in a warm or hot environment. The process won't work in the winter time, or on larger dents in a car.
Bottom Line
Dry ice dent removal is a great do it yourself process, provided that the dents are small, the weather is warm and you use proper safety precautions by wearing thick gloves so that the dry ice doesn't burn you.
