Based on the research thus far it seems that polycarbonate is the right direction to head in. The exact thickness still needs to be determined.
Rain Clearing:
Using a hydrophobic coating may be the easiest solution. Something to consider (I’m not too sure if this would apply to us too much, but we also might want to look at moisture control - like if the glass get’s too foggy for our driver).
Options:
RainX: Easily removes water, frost, ice, muds, bugs. - Nothing on moisture reduction or whether it would work well on polycarbonate (seems glass centered) https://www.rainx.com/original-glass-water-repellent/
NeverWet: Does not let water or oil remain on surface - pretty impressive tbh, but again need to see how it will work on polycarbonate - they have videos on a lot of fabrics. https://www.neverwet.com/applications/index.php
Hirec: They have different series, can contact them for a trial, just to see how it works. http://www.hirecpaint.com/product.html
