Default Lexan windows

Yay or nay?

I can get a set made for the doors. Will still be able to install and roll the window down as OEM. It's basically a copy of the window in hardcoated lexan (macrolon). Saves ~ 5kg per door.

It's a one-off, so about 280. Worth it?

Are they heat formed? There is a curvature to them. I don't know the conversion #'s to US dollars, but $100 for the rear window. Double that for side windows seems a little steep.

is it a track only car? if not, don't do it. you'll go crazy polishing the scratches out. we have a seldom used shop car with lexan on all rear and we have to polish them every time we drive it so we can see out the back.

Yes, formed, cut and coated. Ready to bolt in. $100 for the rear window doesn't include the cutting to size, riveting it all together and the seals right?

And yes, 80% track car. They're hardcoated to resist scratches. There's a cheaper option that doesn't include the coating that would be more track-suited. The coating is supposed to hold up quite well to more daily use.

Yeah, my rear is only a year or so old in the rear and it's getting to be pretty scratched.

Spoolin, what's your method for polishing the window? Anything I can think of beyond soap and water would scratch it.

Yes - the $100 was just for the UV rated Lexan. I did not use seals as that would have outweighed the cost of the project. Rear seals are expensive for what they are. Hardware was merely 5-6 dollars.
I cut the size to shape, I had a rear window to use as a template. So to go out and buy a ready made setup would def. be more than $100
Side windows would be on my list if not too expensive.

They have mild scratch removers (or fillers) I've used in the past on the soft top window with good success. I will have to look to see what it was. And a micro cloth is the only thing I use to clean it. Treat it like you would a face shield on a helmet.

I might get a discount if I get multiple sets made. Shipping shouldn't be overly expensive I think.

I'm trying to get a quote on 5+ sets made. Hardcoated variant should hold up very good even for daily use. If you're interested, let me know.

I have had good luck on headlights and what not with Meguiar's Plastx and a buffer. Freaking amazing results if you take your time.

Rain-x will sometimes work too. It does not polish out the scratches but can optically fill in the voids and make them less noticeable.

Anyone try waxing the Lexan? Seems like it would cut down on scratching a bit.

We use hardcoated lexan for touch screens in the medical industry with great success - it shouldn't be an issue for a car seeing limited use, garaged, etc.

In the next 5 years you'll being seeing hardcoated lexan in OEM vehicles in an effort to save weight/money.

this stuff is the real deal: http://www.novuspolish.com/

I used it to 'restore my Volvo 240 lenses and it worked great and quickly considering I was doing it with my desk-jockey hands.

Where can you find this "coated" lexan? Does the coating hold up under flex like you'd need for the rear window on a hardtop? My rear lexan window is scratched to hell and splitting near the corner after a little over a year.

Definitely wouldn't mind polishing it, but only if I can find something suitable to protect it afterwards. The car sits outside so it'd be a waste of time if I couldn't put something on it.

that novus polish is the best. when the windows are real bad we use a buffer. and to protect it, i wonder if you clear coated and added some flex agent, if it would stick to the plastic?

Like most things, I'm guessing you'd need to scuff it up first. Which would defeat the purpose.

The PlastX is what I was using... will have to look into the Novus. For those that are not parking in a garage and dd... UV rated lexan is the only way to go.

Wouldn't clear window film protect the lexan against scratches?

Add tax and shipping.

These are hardcoated, thermic formed OEM fitment lexan replacements. Remove glass window, install these.

It's what I said as well. Apparently the coating makes it expensive. They do have both NA and NB molds ready though.
