Abstract: A tool apparatus and method of use for repairing dents in sheet metal. The tool contains two elongated arms that extend out of a common housing. The two arms terminate generally in the same plane a predetermined distance from the housing. One of the elongated arms terminates with an interchangeable anvil head. The other elongated arm terminates with an impact head. The impact head is placed below a dent in a sheet metal structure. The anvil head is supported in the exterior of the sheet metal structure over the dent. A motor is disposed within the common housing. The motor moves at least one of the elongated arms and causes the impact head and the anvil head to strike one another. When a dent in sheet metal is placed in between the impact head and the anvil head, the dent is deformed and is forced into the shape of the anvil head, thereby repairing the dent.
