This paintless dent repair kit is perfect for efficiently and cost-effectively removing small car dents without damaging the original paint. Made of stainless steel, the hook rods with flat or round heads are tougher than other rods and not easy to bend. So, you can push the dent from inside effectively. The air wedge, made of durable TPU and nylon composite material, can expand the space between the car window cavity and complete the dent repair. If you use rods to repair dents or bends on the door side, you can use S-shaped hooks and O-shaped rings, with the leverage principle to remove annoying dents or door ding. This paintless dent puller kit can be widely used for car dent, hail damage, door ding, motorcycle, and other metal plate repairs, effectively for big dent repair.
