You are absolutely right, I regretted not filming that!Your video shows removal of the factory anti-glare coating but it does not show you applying a new anti-glare coating. Having shown that part would have been welcomed. I've seen numerous videos on the removal of the stock coating. I've not seen a single video of someone applying a new coating.
I missed it because I applied the new coating about 2 weeks later when I finally took the courage to do it.
The end result is perfect but I guarantee it wasn't fun.
However, I went through all the process with success - feel free to ask any related question and I'll be happy to answer.
If I ever have to do it again I'll make sure to film it.
Thanks for your feedback!
