<div style="font-size:10pt;font-family:arial,helvetica,sans-serif;color:black;"><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">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 be shared:</div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;"><br></div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">Mainly, in an accident, sheets of Lexan or other plastic or even plain plate glass (automotive glass is either tempered or laminated) could break into large chunks and become lethal knife-like pieces that could do real harm. Best to use laminated glass in a windshield. That is why the vehicle makers still use it despite its weight.</div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;"><br></div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">Phil<br><br><br>-----Original Message-----<br>From: Joe via Fot <fot@autox.team.net><br>To: John Davies <john.r.davies@btinternet.com><br>Cc: fot@autox.team.net<br>Sent: Tue, Mar 29, 2022 1:19 pm<br>Subject: Re: [Fot] Lexan windshield<br><br></div><div id="yiv2264422330"><div>We have used a Lexan windshield in a Champcar endurance car for years and have not had a significant problem. The only issue has been when driving for hours in the wet, we would get black streaks near the bottom of wipers like from the rubber transferring to the windshield. After the race we were able to clean it off. Use a cleaner like Nexus to clean it. <div>JoeB<br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Mar 29, 2022, at 4:07 AM, John Davies via Fot <fot@autox.team.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><style><!--

That’s why it’s is unsuitable for a windscreen, and toughened or laminated glass is used. There is no way to prevent road dust getting onto the screen, where the wipers will use it as an abrasive. You might be able to use a water dispersant on the PolyC, and avoid the use of wipers, but constant application will be needed!</p><p class="yiv2264422330MsoNormal"> </p><p class="yiv2264422330MsoNormal">On the surround, consider fitting it <u>to the screen </u>to stretch it first. Then fit the screen/surround to the frame, using the same cord technique, or just take the screen out and proceed as usual.</p><p class="yiv2264422330MsoNormal">John</p><p class="yiv2264422330MsoNormal"> </p></div><span></span><br></div></blockquote></div></div></div>_______________________________________________<br><a ymailto="mailto:fot@autox.team.net" href="mailto:fot@autox.team.net">fot@autox.team.net</a><br><br><a href="http://www.fot-racing.com/" target="_blank">http://www.fot-racing.com</a><br><br>Donate: <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>Archive: <a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive </a><a href="http://www.team.net/pipermail/fot" target="_blank">http://www.team.net/pipermail/fot</a><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/fot/vfracing@aol.com" target="_blank">http://autox.team.net/mailman/options/fot/vfracing@aol.com</a><br><br><br></div>
