I've used both acrylic and polycarbonate for windows, safety shields, cases, and a variety of other things. The pros of acrylic are it's more scratch resistant and has a bit more clarity than poly but the fact that it's easier to crack and shatter offsets its attributes for many uses where impact or vibration may cause it to fail. I wouldn't use it for a window or windshield on a vehicle. But I have made windows and windshields out of poly and it works great for that. And scratches are easily removed with aviation plastic polish. Just be sure to wipe the direction that the wind flows over the glass and never in a circular pattern.

You may be surprised how long a plastic windshield will last. Virtually every aircraft uses plastic windscreens and windows. They may last for decades if taken care of. And most aircraft sit outside in the elements including dust storms. But if you don't know how to properly clean them you can ruin them in a matter of seconds.

Well cpap, you got your work cut out for you. But if you ever want to try plastic again, here's the world's best cleaner & polish (at least the best I've found in four-decades of flying). Use it on your helmet face shields too. It will take out small scratches but not the deep ones. NEVER use a circular motion cleaning plastic windows, make the strokes the same direction as the wind goes over the windshield.

Want to get rid of bugs and other stuck on debris -- use Pledge furniture polish. Works on painted surfaces too. Flying search & rescue at low altitude in the mountains during the summer months and you hit thousands of bugs. Pledge makes an impossible job of cleaning bugs off windscreens and leading edges a piece of cake.

Good luck.

I don't use plastic off-road cuz of the dust. Dust is attracted to the plastic but even glass windshields get coated with it. I have tried a couple anti-static products in the distant past. Don't remember which ones but they were a failure. NASCAR uses plastic windshields and apply tear-offs to them. Just like the tear-offs for your face shield but bigger. That could be an option for mud, bugs, and debris on the outer side but not practical on the inner side. I think what you'll find is that the dust coats the inside of the windshield more than the outer surface.

I really can't guestimate the difference in scratch resistance between acrylic and poly but it's different. And the propensity of acrylic to shatter is also real and will be something to deal with. You might want to go thicker with acrylic. I used 1/8" poly on my drag car -- could never get away with that in acrylic. If you're cutting your own, heres a trick to clean up the edges. Use one of those cheapo-depot butane torches and carefully heat the rough edges and it will melt to a smooth finish. Go too much and you will discolor it so practice on scraps. Try to keep the flame from touching the plastic. In my previous life I used these plastics quite a bit fabricating guards and shields for manufacturing equipment.
