Non-toxic, two-part epoxy putty used as an adhesive bonding to metal, wood, glass, masonry, ceramics, most plastics, and underwater surfaces. Seals leaks in pipes, tanks, ductwork seams, and air conditioning coil. Fabricates new or used parts, repairs auto-body damage, replaces solder or welds, tape, and ceramic connectors. After one hour it can be drilled, tapped, filed, sanded, and painted over. Any unused portion keeps for over one year.
