...so is my windshield 'hard' coated? Anybody know?

Post by Farmboy57 »



A number of members have asked about how to clear up their foggy, hazy, or lightly scratched oem windshield. I'm another one. My windshield is getting hazy (ignore the dust from my last ride). To make it clearer again, should I wet sand from 1000 grit to 2500 or higher? Is a product like Novus effective on a hard coat? is it hard coated? Plexus to the rescue? All of the above?
Here's all the info presented on the oem windshield on my 1990 Gl1500SE:

AS6 M-121
GE
LEXAN FMRSHEET
DOT - 94


it's Greek to me, and I've spent enough time splashing around on the internet trying to make sense of it. Anyone know how to read it correctly to give their opinion on the best way to proceed?

I do not think it is hard coated.
I've used Novus with good results. Give it a try.
Plexus is not a polish, or at least not so you can notice. It cleans pretty good and leaves an oily film to help keep the bugs from sticking but that is about it.

Don't try to sand Lexan!

Lexan is polycarbonate. Polycarbonate is different from Plexiglass, which is acrylic.

Polycarbonate (Lexan) is stronger than acrylic (Plexiglass), but it is also softer. For that reason, polycarbonate always has a hard coating on it to protect the softer inner polycarbonate from being scratched.

If you sand or use abrasive polish on polycarbonate, it will take this hard protective layer off, and you'll end up destroying the soft polycarbonate underneath.

So is using Novus 2 and Novus 1 the right procedure? I can live with the windshield the way it is, upon close inspection it looks like it may have met paper towel and window cleaner numerous times over the past 3 decades. If I make it worse I'll replace it next year, but I'd like to try and bring it back. Actually, just tonight, on closer examination, what I thought were small amounts of remaining residual adhesive from some silly chrome trim I removed from the perimeter of the windshield turns out to be missing coating (guess it's hard coated). It's either live with it or put more chrome trim on. I'll live with it. But I believe the slight haze is do-able with the Novus products. I've maintained my windshields quite nicely with Plexus for years, but I've always been told Honda cleaner is just as good..at a third the price. Won't know till I get a can.

Read my post above. Don't try to abrasive polish Lexan! You'll end up destroying the windshield.

I stand corrected. If it is in fact Lexan as the markings indicate, it does have a hard coating. Novus will probably not help you at all.
I do know that on Honda OEM windshields and Tulsa and Tulsa Style Windstreamer Windshields, the Novus 2 works quite well.
