Automatic Taper/h2> aka a "Drywall Bazooka" that simultaneously applies joint compound (mud) and drywall tape to seams and corners, significantly speeding up the drywall finishing process compared to taping by hand. It works by loading a roll of paper tape and pumping mud into its internal tube; as you run the tool along a joint, it dispenses the mud onto the seam, lays the tape over it, and has a cutter for the tape, making the process much faster and safer.
