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