Why is my spray gun not working?

If your paint gun is not spraying paint at all, it’s most likely due to a clog either in the air vent hole or the hose. Clean any dried paint with a toothpick, and use a cleaning solvent to clear any remaining gunk. If you’ve cleaned your paint gun and find that it still isn’t spraying, take a look at the air supply.
