Motor Guard’s Magna-Stitcher (Model MS-1-KIT) provides an economical solution for plastic repair by turning your stud welder into a plastic repair tool. The MS-1-KIT fits all popular stud welders and provides all the features of a plastic repair system at a fraction of the cost. It works by welding a rigid stainless steel stake into the surface of the plastic, resulting in a permanent repair of the crack. Repairs can be made on flat surfaces, tabs, holes, ribs, and inside and outside corners. Once the back of the broken part is stitched, the cosmetic repair and refinishing can be completed on the outside of the part.
