<br/><br/> The research Development of Spray Gun Paint Mixer Reservoir Cap seeks to demonstrate<br/>the feasibility of correct paint combinations, which will assist students and painters in<br/>avoiding time-consuming and messy painting jobs. Furthermore, the device promises to<br/>improve reservoir cleaning without the use of excessive thinner. Paint mixture is one of the<br/>most commonly used methods in the automotive industry, with various variants such as<br/>matte and glossy finish. It has also been used and developed in technology in the way paints<br/>apply, with powder coating or wet applied coating becoming a technique that has been<br/>populated globally. The mixing theory and device operation eliminates dirty work in<br/>automotive paint mixing. It contains a charging connector, an on/off switch button, an LED<br/>indicator for battery status, and a simple locking mechanism. It also includes an improved<br/>charging procedure that uses the 3.7-volt battery to power the 9-volt DC motor. For the<br/>charging system, the device employs a TP4056 module and a Step-up module, 12millimeter<br/>bearings for shaft fittings, and a 9-volt DC motor that powers the propeller stirrer. Test<br/>results showed that the device could be used in any paint mixture in automotive painting<br/>and the paint industry without issues, and the test data were processed as expected in terms<br/>of speed and accuracy. The device was evaluated by 35 evaluators composed of power plant<br/>professors, professionals, and students under the Power Plant Engineering Technology<br/>Department of the Technological University of the Philippines —Manila and was rated<br/>with an overall mean of 4.61 and a descriptive rating of "Excellent". This signifies the<br/>device's usefulness to all students and painters in terms of mixing paint straightforwardly.<br/>Keywords: Spray Gun, 3.7-volt battery, 9-volt DC motor, TP4056 module, propeller stirrer,
