How Are Car Dents Corrected With Heat?

The most straightforward method for straightening a dent is by pushing it from the back panel. However, it is essential to give way from the backside of the dented panel and push it with your hand or some tool into the middle of the dent. In addition, you can also use the heat transfer method to heat the dent's edges and relieve the stress on the metal.
