A spray gun with a powder spray nozzle sprays a pattern of coating material through specified discharge slot configurations to evenly coat a recess and/or the surface of a substrate. One discharge slot configuration, having two intersecting slots disposed at substantially sixty degree angles to each other, can be rotated to change the width of the coating being applied within the recess. The other slot configuration, having at least five radial slots and a substantially circular bore extending through the intersection of the slots, is effective to coat both the recess and the flat surface of the substrate.
