What is the best DIY dent removal method?

For DIY car dent repair, the most effective method currently is to use a hot melt adhesive scratch-free repair kit, such as the JCOTTON 97-piece set or Sigoobal tool kit. These kits use high-strength hot melt adhesive and a bridge-type puller, which can safely adhere to the paint surface and pull out dents without damaging the original factory paint. When operating, first clean the dent surface, apply hot melt adhesive to the pull tab and press it onto the dent. After the adhesive solidifies, use the puller to apply force slowly. Finally, use alcohol to remove any residual adhesive. If the dent is shallow, you can try the toothpaste polishing method (only for scratches where the primer is not exposed). Squeeze out ordinary white toothpaste and polish in a circular motion for 3 minutes before wiping it off, but this method should not be used frequently. Using the principle of air pressure difference along with a bridge-type suction rod to gradually pull the dent flat, you need to pay attention to applying force evenly to avoid excessive bulging. If self-repair is difficult, It is best to seek professional scratch-free repair services, which use metal micro-shaping technology to accurately restore the shape of the panel. The price of tool kits is usually between 80 and 300 ringgit, which is more cost-effective than traditional sheet metal painting.
