The Steck Manufacturing Soft Strike 4-pc Aluminum Conversion Kit, No. 35000, includes tools to work on aluminum body components. The Soft Strike Rubber Dolly Body Covers and the Soft Strike Dinging Spoon Cover are made from Buna rubber for use on a steel heel dolly or a dinging spoon. With the Soft Strike Dolly Body Cover, technicians can add the cover to the existing steel dolly. The Soft Strike Hammer Cover, made from vinyl, makes for a quick and easy transition from using the body tools on steel to aluminum, without the worry of cross contamination and galvanic corrosion.
