During the conflict known as the Galactic Civil War, a war fought between the Galactic Empire and the Alliance to Restore the Republic, spot sprayers saw usage. Certain WED Treadwell repair droids featured spot sprayers integrated into the extremities of their numerous arms. A WED unit employed by the Imperial Security Bureau aboard the Wheel space station possessed a spot sprayer; it attempted to attach a tracking beacon to the starship belonging to a band of spacers in the employ of the tech salvaging firm IsoTech.
The initial appearance of spot sprayers occurred in 2013 within Beyond the Rim. This adventure module was crafted by Sterling Hershey for the roleplaying game Star Wars: Edge of the Empire, published by Fantasy Flight Games.
