I'm still really happy with this product and performance of Optimums Consumer (non Pro) Glass Coat product.
This One:
Optimum Opti-Glass Coating
It is by far the most durable glass coating I have used. I have used G1/G2, Aquapel, rainX and permanon glass.
Of the others, aquapel would be my 2nd choice but I'm sticking with Optimum. This glass coating you see in the video has 40K on it as well as the 20 Months
Recently picked up a new bottle to top up the other cars before the winter.
