Pneumatic needle guns are rugged tools. They are designed to be easy to use and maintain. They are ideal for removing layers of paint, corrosion and chemical coatings etc., from metal and non-metal surfaces. These tools work well on irregular surfaces and in crevices and corners. The needles are heat treated and are quickly replaceable.

It is automatically adjusts 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 in terms of accuracy and precision. Prior to painting, it is desirable to feather any edges between metal and old paint. Since bare metal surfaces will flash rust soon after exposure to the atmosphere, paint should be applied as soon as possible after chipping. If flash rusting occurs prior to coating, further chipping, cleaning, and sanding may be necessary.
