The greatness of YouTube is the amount of quality content it contains and how much we can learn by watching certain videos, something that is perfectly fulfilled with the video that I present in this post.
El Engineer Guy teaches us how Apple applies color to aluminum anodized and the reason for the high resistance of this material to scratches and blows, something that I have been able to verify first hand and that I confirm without any doubt.
The video is in English, but I still highly recommend watching it because it is very visual and does not require great knowledge to understand what it explains.
