Clean the dented area of the car with a clean, damp towel; insert the hot melt glue stick from the back into the hot melt glue gun to melt the glue from solid to liquid. Select an appropriate suction puller pad, pull the trigger of the glue gun, and evenly coat the pad with melted glue using the electric glue gun. Quickly attach the hot melt glue-coated suction puller pad to the center of the dented surface, press lightly and hold until the hot melt glue solidifies and adheres firmly. When the glue is no longer sticky to the touch, connect the suction puller to the suction puller pad, hold the suction hammer of the puller with your left hand, and pull the handle of the puller outward with force.

Last time my car door got a small dent from the neighboring car's door opening. After researching for a long time, I discovered this amazing paintless dent repair technique. The technician used a specialized lighted tool to slowly push the dent out from inside the door panel - the whole process was like performing minimally invasive surgery. The best part is it preserves the original factory paint, leaving absolutely no trace after repair, perfect for coin-sized dents. The technician explained it works by utilizing the metal's elasticity to restore its shape, but severely deformed areas still require traditional bodywork. If your new car gets dented, I highly recommend this method - my Lexus looked brand new after repair, even a paint thickness gauge couldn't detect any difference.

Watched a repair shop use hot glue sticks with a puller to fix bumper dents, quite an interesting DIY method. First, apply paint remover to the dented area to protect the car paint, then stick on the traction pad and slowly pull it out. Friends with a garage can buy a set of tools to try it themselves, but it's only suitable for plastic parts and single-curved metal parts. Remember when my neighbor uncle over-pulled while repairing the hood and had to hammer it back in the opposite direction—never use brute force on plastic parts. This repair method saves the painting step; just wipe off the glue marks with alcohol after fixing.

The dents on my car roof caused by hail were repaired using micro-dent repair technology. The technician used a hook to reach inside the roof lining and precisely pushed the dents out, much like performing acupuncture. According to the repair guy, the key is to find the right pressure points—if the metal deformation exceeds 30%, filler and repainting would be necessary. Nowadays, auto repair shops even have automatic dent detection devices, which are far more accurate than the naked eye. That repair cost me 800 yuan, but it was much more cost-effective than a full repaint. Preserving the original factory paint can add thousands to the resale value later on.
