Abstract
A sealant applicator nozzle, of the present technology, has a fan-shaped profile, with a broad concave arc that defines a distal end of the nozzle and provides the nozzle with a tooling edge. The concave tooling edge, along with the outlet orifice, and two surface-contact edges are positioned to equidistantly straddle a lap joint to be sealed when in operation. In methods of using the nozzle, a wide ribbon of sealant is applied in a smoothly arched geometry, forming a segment of a circle, over a lap joint so that the thickest part of the arch is centered directly on the edge of the overlapping material that forms the lap joint.
