Paint Gun (Fallout 3)

The Paint Gun is a miscellaneous item $$

Gameplay
Paint Guns are a common, semi-valuable junk item. In Fallout 3 they are used in the construction of the Dart Gun or used as Rock-It Launcher ammunition. In Fallout: New Vegas it serves only as a miscellaneous item with no known uses.

Locations
Paint Guns are found throughout the Capital Wasteland. They are reliably found in toolboxes, metal boxes, around workbenches, and in raider camps. They are also sometimes sold by "miscellaneous" vendors like Crazy Wolfgang, Knick Knack, Karl, and Seagrave Holmes. Some guaranteed locations for Paint Guns:
