Steck 20017 Super Seambuster - Can now be driven by means of an air hammer to separate spot welded or bonded panels. (Note: Spot welds must still be drilled out first before using Super SeamBuster or any SeamBuster product). The Super SeamBuster is designed to attach to any air hammer for faster and more efficient separating of quarter panels, rockers, bonded door skins, and any other pinch welds. It is sharpened on two edges. The top sharp end allows for penetration between the panels and the lower edge allows for side impact to drive the panels apart.
