An apparatus for modifying a defect in a surface may include a hollow shaft including a first open end and a second open end opposite the first open end, a plunger slidable within the hollow shaft and extending from the first open end, a driver coupled to the second open end of the hollow shaft and extending from the second open end, and a passive resistance mechanism coupling the plunger to the hollow shaft. The passive resistance mechanism biases the plunger towards the second open end of the hollow shaft. The plunger has markings thereon that are visible when the plunger is extended from the first open end. Methods for using the apparatus to modify a defect in a surface are also described.

A paintless dent removal tool for removing a dent from a vehicle is disclosed. In some embodiments, the paintless dent removal tool includes a stabilizer assembly having a first leg, a second leg and a body therebetween. The body having an opening therethrough, the stabilizer assembly for stabilizing the paintless dent removal tool on a surface of a vehicle. The paintless dent removal tool including a pull bar having a first end and a second end. The first end of the pull bar positioned partially through the opening of the body of the stabilizer assembly and adjustably connected thereto.

Provided are a steel-shape measurement device and a steel-shape correction device. The steel-shape measurement device measures a distance to a detection spot group on a to-be-scanned surface of a steel product with a laser rangefinder 5A that measures the distance through scanning of a steel product S with a laser beam emitted from one laser light source 11 and redirected with a galvanometer mirror 13, and measures a shape of the steel product from obtained measured-distance data. The steel-shape measurement device includes an object having a 45-0 diffuse reflectance of equal to or lower than 10% as a laser-beam absorber 8 at least one portion within an irradiation range irradiated with a regular-reflected laser beam from a to-be-scanned surface of the steel product.

The disclosure discloses a wheel rim straightening device. The wheel rim straightening device includes a lifting platform; the lifting platform is symmetrically provided with a left horizontal sliding table and a right horizontal sliding table; the left horizontal sliding table and the right horizontal sliding table are each provided with a vertical sliding table; and the two vertical sliding tables are provided with an inner pressure head which extends outwardly and corresponds to an outer pressure head, and a first runout detecting gauge corresponding to a second runout detecting gauge.

A dent removal teaching system may include a base frame and an upper frame movably coupled, or articulating with the base frame. The upper frame may include a plurality of access holes, whereby a dent removal tool may be inserted into one of the plurality of access holes. The dent removal teaching system may also include a body panel which may be releasably secured to the upper frame, so that a user may apply force to a dent in the body panel using the dent removal tool. This combination provides a teaching environment to practice the removal of a dent from a vehicle body.
