Does this guy make it thru the video without frying his brain on Carbon Monoxide, and if so how?
The LAST thing you want on your vehicle is an "acrylic" windshield. Lexan ... maybe. Acrylic ... no F'n way !!!
The difference being Lexan is "shatterproof" ... you fire a bullet at it, it makes a big dent and a small hole. Acrylic (plexiglass) is NOT shatterproof - you fire a bullet at it and it shatters into shards and slivvers.
They line up to buy his swag though !!!

Most GA aircraft windshields are cast acrylic.

I was always told Lexan is very hard to heat form, mainly because the temp forming window is very narrow, whereas acrylic is very doable.
So, for a show car I can see why one is chosen. I also have my doubts if the scratch resistant Lexan can be formed at all. Don't know.

Polycarbonate is very tough to form. There is a lot of moisture in polycarbonate that creates bubbles if it’s not heated slowly for a long period of time to get it to dry out.
So are the canopies for fighter aircraft. That still doesn’t mean you should use it for a windshield !! I suspect the likelyhood of a stone chip at an altitude of ten feet or more is a lot less likely !!!
Acrylic has a higher natural UV tolerance. That may be one reason they use it in the aircraft industry - less deterioration in a given amount of time. It’s also more rigid so won’t deform under pressure as much as polycarbonate will.
