Some tips for removing dents from cars include using dry ice and a hair dryer to induce a temperature change that pops the dent out and using a hot glue gun to attach handles to the dent and pull it out. Another tip for removing dents is to use a blow dryer and compressed air to fix the dent.
To remove dents from cars with dry ice, you need dry ice, a hair dryer and gloves. First, heat the dent using the medium setting on the hair dryer. Keep the hair dryer at least 5 to 7 inches away from the car's surface to avoid damaging the paint job. Apply heat to the dent for 1 to 3 minutes until the spot is warm to the touch.
Put on your gloves and apply dry ice to the center of the dent. The abrupt temperature shift forces the dent to pop out. Repeat this process a few times until the dent is fully gone.
Another way to remove car dents is to use a hot glue gun to attach handles to the dent and manually pull the dent out. Drill screws into wooden dowels to create handles. Using the hot glue gun, attach the dowel handles to the car in areas surrounding the dent. Allow the glue to cool for about 20 minutes and then pull each dowel off the car, removing the dent at the same time. Pull the dried glue off the car when finished; the glue does not impact the paint job.
