Hi!... I have created a simple locker material; it is available in 4 or 5 colors. There's also a Graph and an SBSAR available to change their colors, increase dirt and wear, three simple yet very practical parameters. 
By the way!... I made the audio for the video myself... if anyone wants to have the audio for their video presentations done, feel free to contact me!! Thanks for reading... hugs to everyone!
