Abstract: “The dent removal industry utilizes specialized tools and techniques to remove automobile dents. This invention is unique because it uses strong magnet(s) attached to the tool tip introducing a magnetic field thru sheet metal. The magnetic material can be neodymium iron boron (NdFeB), samarium cobalt (SmCo), or other strong magnetic material. A magnetic dust applied on the painted surface of the sheet metal near the dent indicates the tips position. Sliding the tip on the underside of the sheet metal near the dust and dent collects the material at the tip's position. Identification of the tip's location reduces the number of pressure flexes, eliminates the need for specialized lighting, frees the technician's posture, and does not require extensive and costly training. This invention and technique greatly improves the ease, accuracy, and speed of removing dents. Untrained individuals can thus remove dents.
