New Air Hammer driven door skinning tool that is easily affordable for every Autobody technician. Skins doors in less than 10 minutes using Skin Zipper’s self lubricating reinforced Nylon head that will crimp regular or adhesive bonded skins. The Skin Zipper crimps the edge tightly for a professional finish with no damage to the skin in an easy two step process. 1. Step One allows the technician to form the edge of the door skin to an initial 45° angle by holding the tool at a right angle to the door. No hammer and dolly work required here. 2. Step Two allows the technician to complete the final form by using the tool at a 45° angle. Two side slot widths are included for thick or thin sheet metal skins. When completed minimal finishing may be required on the corners and body lines. Skin Zipper reduces technician arm fatigue from hammer and dolly method as well as door refinishing time. The head will skin approximately 10 door skins and is easy to replace when it wears out.
