All of my Lexan windows have developed a surface roughness to them that reduces visibility. I've tried various polishes, cleaners and rubbing compounds with no success. My first reaction was that I used some type of window cleaner on them that damaged the surface however my side windows have not seen any cleaners and are doing the same thing. The only time the car is exposed to sunlight is when I have it at a track event. I keep it covered the rest of the time.

Would wet sanding help or is it end of life for the materials?

depends on how old they are. i try my best to never touch the lexan windows unless i absolutely need to clean them. my back window was just cleaned last week for the fist time ever and i installed it at the beginning of this year. every time you wipe them down they get little streaks, even if you use a microfiber towel.

that's about all i know about windows i'm sure some of the more experienced people on this board can comment on how long they last.

I think lexan is too soft to polish but try a small area with McGuire's headlight restoration polish. Best advice is to not touch them unless you have to.

The coated windshield on my stockcar had the coating start to degrade and flake off but it was very old. Nothing worked on the coated stuff. I replaced it with non coated lexan and have already scuffed it a little by putting a tarp over the car and towing it on an open trailer. Looks like that might clean off with McGuire's headlight restoration polish but haven't gone after much but a small area so far.

don't try and install tear-offs yourself. i did this and it bubbled so bad i couldn't see out of it. i used to tint car windows when i was younger so i thought i could do it. when i pulled the film it left miles of glue and the window was trashed.

They will wear out overtime and you will have to replace them. I don't know if I have seen one last forever.

This is what I used on our cars through the season though.

Works pretty well if you stay on top of it.

Novus works well. They make cleaners and polishes.

Had great luck with Plexus for maintenance on aircraft and motorcycle windscreens.

Works well on headlight lenses also.

Thanks guys, I'll give Novus and Plexus a try. I've already tried the Mcguire's headlight restoration kit with no luck. Window may be beyond saving.

I have a Novus kit that I used on my Stock car. Still had to replace the windshield every year, but I would polish it during the season. Stuff works great ! I even use it on my eyeglasses !

How long did you get from them? Im considering a rear hatch glass

Lexan windows in general are not very durable in terms of scratches and overall clarity, but if you buy molded ones from Five Star or similar, they have a coating that seems to help. I personally run a glass windshield because it's less hassle, but when we were running lexan I always kept a thick tearoff (~$60) on the car. It made the windshield a 4 year replacement item rather than yearly.

The windshield and rear hatch window came with the car. I added side windows for transportation. The side windows lasted about 2-years. This year, I replaced the Lexan windshield with a glass windshield. It had degraded beyond the point of serviceability. I'll get another year out of the rear window. All of the Lexan products were from 5-Star.
