Old Speckled Framer

Sometimes when spraying gesso, there will be a clog; a little something in the tubes. The easiest way to clear the clog is to gently place a finger over the nozzle so there is blow back, that will clear the clog, gently being the operative word. Done properly, this will clear the clog, and not blow a burst of gesso out the vent. Tah Dah! A tip of the hat to Moreland brewing and their delicious in the widget cans.
