An spray gun extension used in the application of liquids such as paints and other coatings, cleaning solutions, solvents, blasting agents, solvents, sealants, lubricants and pesticides in high volume low pressure spraying. The extension allow the application of such liquids to areas above, below, around, behind, or into devices or fixtures not visible and otherwise inaccessible to the applicator. The extension is rotatively mounted to the spray gun. A spray head is rotatively mounted on the extension. A variety of spray nozzles may be used, including a fixed nozzle, and a nozzle which may be used to vary the spray pattern width and fan shape. Liquid flow is controlled by a needle valve near the end of the extension. The extension may be used to spray straight ahead or at any angle including back toward the spray gun.
