ABSTRACT:
A repair kit for removing dents from a sheet of metal. The kit includes a sheet of damping material that is mounted to the surface of the metal. A vacuum can be pulled between the sheet metal and the damping material so that the surface of the damping material is secured to the metal. An electromagnetic device is inserted through an access hole in the damping device and energized to pull the dent out of the sheet metal. The damping material dampens any vibrational energy generated in the sheet metal and prevents "spring back" during the dent removal process.
