Default Lexan

I appolagise for my previous post, $400.00 for a malibu, all windows including the windshield is a very good price when Margauard is included. My Malibu is all factory glass, but if i decided to go lexan/marguard, i would pay $400.00 for the conversion.

Just my .02

Im not sure the margard stuff (or equivalent) is so much better than the regular lexan, I have seen at the track lots of cars that you wonder how they can see going down the track.
And night racing under the lights with a lexan windsheild can be very annoying. Lots of light distorsion.
In my opinion and experience, I think it is better to leave a stock glass windshield in the car and use the polymer on the other windows. Just makes it soo much easier to hit the light at a night race. For the few lbs you save, I would rather have good visability out the front.
However, if you got a full on fiberglass car such as brians, you dont have a lot of choice... :lol:

you really don't want to get in a wreck with the real glass window in the car.
Hit the wall and let the windshield shater--- no fun !!!

I had a lexan windshield on my motorcycle and it was scratched on both sides. Very bad glare, especially at night, and in the rain. Same with shield on my helmet. The fix is to clean it spotless and I mean down in the scratches also. Then many coats of Armor All or Rain-X. Rain-X lasts longer.

I am in agreement with the Margard lexan. I chose the Home Depot kind because of a few reasons. 1st was that my car will be a 9-10 second car if I ever decide to go that route. Probably high 10's will be its limit. I am also leaving the front windshield(new and stock) in place. I wanted to try to get stock glass installed in my VFN glass doors,but that can't be done.So, I looked around (before I found RJ) and couldn't locate anything for my car. They had kits for Chevelle and nothing for a Buick GS.Before anyone starts saying they GS is the same as a Chevelle,you would be wrong! My front window and possibly side windows are the same,but the rear glass is totally different. It sucks that I have to scrounge up Chevelle parts and modify it to fit my car,but thats how it goes. 2nd,even when I found the kits they were 7-8 hundred bucks a set and shipping was astronomical. I realize the Camaro,Malibu etc guys are the most common cars and I always have to pay a premium to have such an (ODD??) choice of car. I am used to it now and just pay the extra premium.I am just hoping to get started with the Home Depot stuff till possibly I can get some Margard material.
To get off topic a little,where do you guys get your mounting kits and hardware to mount your side glass?? I have located a kit from S&W racecars but nowhere else.

Default big difference

There is no comparison bettween Lexan (or any other manufacturers Polycarbonate sheet) and Plexiglass which is an extruded Acrylic sheet. I believe Lexan was developed for fighter canopies. You cannot break Lexan. I have seen guys take a ball peen hammer to it and it simply WILL NOT crack, shatter, etc. Plexiglas on the other hand WILL crack, shatter, etc. Home depot sells Acrylic sheet, that's why it is so cheap. Your OEM windshield is laminated with a plastic layer in the middle that adheres to the glass and retards glass fragments form entering the vehicle with any breakage. NEVER put anything but Lexan (Polycarbonate) in a windshield application. Anything but Lexan would be very Dangerous!!! From a safety standpoint, I wouldn't use Plexigas for anything on a car. Your side and rear glass is tempered so that if it breaks, it crumbles and there are no shards of glass. Plexiglass will shard, and therefore is dangerous in an automotive application. You will have clarity problems with anything but glass. That is just the tradeoff for the weight savings. You can either live with it, or you can't.
