My windshield has some wear from the wipers. but no cracks

Can this be polished? or is there some coating that would be ruined (more) by trying.

When I did the car I left the windshield in, and really have no reason to change it out now. But I would like to eliminate some of the fine scratches from years of wear.

Ive heard of a process to polish windshield glass but have never seen the result or tried it myself.
Quite honestly by the time this option is being considered you are probably better off replacing it.
Aside from the wiper wear, there is probably also a thousand micro chips that make visibility at night maddening!

I’ve heard of it through Paterak in Chatham, NJ about 20 years ago. Very tedious, time consuming and prone to error but can be done I was told. Similar situation with my original windshield but I’m probably too impatient to do it myself successfully.

I’ve had good results with the Eastwood glass polish kit. Took out some wiper wear scratches. Wow the price went up!
I think I paid around $50 something about 4 years ago.

Water spots can be removed but small sand blast chips will never polish out. I used black car wax and that helps hide small imperfection but doesn’t last very long

The windshield on my beater Malibu was very scratched up..I used a glass polishing pad with my random orbital polisher and had great results.

Griots glass polish kit and a DA did an awesome job getting minor scratches out of my glass. Anything you can feel with your fingernail is probably beyond polishing….

Just as an aside.
What works on windshields does not work on the door or rear glass.
0 results with hours spent using the kit that works on windshields.

New windscreen is the only way. I have been in the glass/glazing biz for many years. There is no polish we have found and we have tried many. My local guy charges me $350. new windscreen installed, why fool around with snake oil

Not necessarily snake oil. The pads do work, but they can't be too aggressive or they require more stages and even more time. The general rule is if you can catch it with your fingernail replace. Now if it's an original and you have 10-12 hours to work on it, polishing may be the way to go, but it is a slow process.

Good to know! 1 hour maybe twice a week and it’s done in 5-6 weeks and able to keep original windshield and markings. Maybe not 100% perfect as new, but can live with 80-90% for sure! (IMG:style_emoticons/default/beer3.gif)

I had a buddy start doing mine before I could stop him (I was inside taking a piss at the time) during a garage session. It didn’t hurt anything. Secondhand anecdotally I have a glass guy that has said it can work.

To the others saying just replace the glass, I think there is something to be said for having original glass in the car with oem stamps. There is also risk involved if you break it while replacing which is not a likely possibility if you take your time, but it’s a risk nonetheless.

There seems to be a lot of YouTube videos that may show you what's out there and how it's done. Looks like the key thing is to go slow and keep it cool.
