You usually got some airflow over the visor inside on motorcycle helmets so the fog-stop coating can rely on that to work. So that fan is needed to get the airflow backHello! My paint scheme is just a custom design. I saw one online and changed it a little to what I thought looked good.
For the visor, I just used a motorcycle helmet visor that I got on Amazon. I had to cut it with a dremel tool because it was kinda thick. The visor said non-fogging, but it still did fog up a little to be honest. I would definitely recommend installing a small usb powered fan in your helmet to cool you down some. You can power it by getting a usb battery stick. I got both from Amazon and I showed it in my first video.
