Our final pick is sold as a complete kit that can be used to spray unthinned paint using adjustable pressure that ranges from 1000 PSI to 3000 PSI. The Krause and Becker kit is packed with a ton of features including a high pressure piston pump and a practical twist knob that allows you to control this pressure. The powerful motor allows you to draw directly from small one-gallon containers to larger five-gallon ones. This design is also equipped with a trigger lock, making it easy to clean and maintain the spray gun. This kit is far from heavy and is ideal for outdoor use as well as indoor use. The unit itself is made of heavy duty and corrosion resistant stainless steel and the gun is equipped with a filter to get rid of debris found in certain paints.
