Stay-of-the-Art Repair Tools: For most hail damage, professional auto body shops can use what is known as paintless dent repair (PDR). The PDR process requires trained technicians to use metal rods of various sizes and shapes to work and push each individual dent out of the vehicles surface from underneath.

While heat can cause expansion in metals, the dents caused by hail require targeted repair techniques to restore the metal to its original form. In other words, relying solely on sun exposure to remove the hail dents and dings may only cause further complications. Your car may start to look worse, especially the paint.
