Then, the needle gun is used to remove rust, loose scale, and paint, leaving bare metal. It is used most effectively by holding it at a 45° angle to the work surface. It is recommended that an area no larger than 6 to 8 inches (150 to 200 mm) be cleared at once. Two to three passes over an area is generally sufficient to clean it. Then the process is repeated until the desired area is completed.

The needle gun has advantages over other scaling tools. Its main advantage is that the needles automatically adjust themselves to contours, making the tool a good choice for cleaning irregular surfaces. A needle gun can clean an area to bare metal in seconds, and compares well to other scaling tools

Prior to painting, it is desirable to feather any edges between metal and old paint. It is also important to check the surface for oil deposited during chipping, and if necessary, clean the area with solvents. Since bare metal surfaces will flash rust soon after exposure to the atmosphere, paint

A needle gun has a set of very fine chisels known as needles. The tool forces these needles against a work surface at variable speeds up to around 5,000 times per minute. Different models offer choices of number of needles, operating speed, and power levels. Many models use

Because the power tool is noisy and can produce flying chips of debris as well as fine dust, PPE to protect vision, hearing, and breathing are recommended by safety regulators and tool manufacturers.
