A. [Environmental protection]: It causes little to no damage to the car paint. The paintless dent repair technology can remove dents relatively efficiently without repainting the vehicle surface. B. [Durability]: It is made of high - carbon stainless steel, which can withstand metal pressure to a certain extent without easily bending or breaking. The dent puller is made of corrosion - resistant steel to reduce the risk of rust and maintain a decent appearance. C. [Wide application]: The dent repair tool is suitable for sheet metal processing of various items such as cars, refrigerators, motorcycle bodies, washing machine bodies, etc. Different - shaped heads can be used for different types of dent repairs. D. Tool usage method (taking the car door as an example): - First, roughly determine the range of the dent. - Then, insert the air pump bag into the car door gap, squeeze the air pump ball so that the air bag expands and the gap becomes larger. - Next, insert the red wedge into the gap and remove the air bag. - After that, select an appropriate puller and insert it into the gap. - Aim at the back of the dent and apply pressure to the dent. - If there is a bulge on the surface, select a suitable pen or nylon pen and a hammer, and gently and repeatedly tap the bulging surface until it appears relatively flat. - If the dent and bulge still remain, repeat the above step until a satisfactory result is achieved.
