We have used a Lexan windshield in a Champcar endurance car for years and ha=
ve not had a significant problem.  The only issue has been when driving for h=
ours in the wet, we would get black streaks near the bottom of wipers like f=
rom the rubber transferring to the windshield.  After the race we were able t=
o clean it off.  Use a cleaner like Nexus to clean it. =20

As one who looked into glazing materials for all cars as a research project=
, I have some misgivings about Lexan or other plastics that I feel should b=
e shared:
Mainly, in an accident, sheets of Lexan or other plastic or even plain plat=
e glass (automotive glass is either tempered or laminated) could break into=
 large chunks and become lethal knife-like pieces that could do real harm. =
=C2=A0Best to use laminated glass in a windshield. =C2=A0That is why the ve=
hicle makers still use it despite its weight.
