Lexan is not a very good choice for a windshield. While it is extremely
durable, it scratches VERY easily. Hence the use of tear away shields
on helmuts, etc. that use lexan lenses. Running windshield wipers over
it with any dirt at all will quickly etch it, and AFAIK, you really
can't polish it. When I asked a shop that build racecars why you
wouldn't use Lexan, that was one of the top reasons that they wouldn't
do it even if they were allowed to. Other reasons not to use it is that
it flexs and distorts, and is difficult to fasten and therefore
difficult to change quickly in race.
