A coating for windshields is a lot more difficult since it has to be transparent, ability to be abraded by windshield wipers constantly
Yes you can see that after some years. My car is not 3 years old (sadly not a Tesla one) and if it rains you will see the difference between the areas on the windshield where the wipers works and "scretch" the glas and the areas where no wipers.
And this is the problem, lets say challenge not always talk about "problems" to design a coating that is easy to get hard bonded to the glas surface. The coating should lasts slow, resists the scratching of wipers and ice and should has the properties of hydrophobic behavior.
