A dent puller is a tool used to remove dents from metal surfaces, typically on vehicles. It works by using suction to pull the dent out, restoring the metal to its original shape. Dent pullers are available in a variety of sizes and shapes, depending on the size and location of the dent.
Dent pullers are a relatively simple tool to use, but they can be very effective at removing dents. They are also relatively inexpensive, making them a good option for do-it-yourselfers. However, it is important to note that dent pullers will not work on all dents. Dents that are too large or too deep may require professional repair.
