Does anyone have experience with a DIY windshield polish kit like this?
!!! UNKNOWN CONTENT TYPE !!!
The glass on the Passat is terribly scratched and it’s making night driving difficult. I’d like to avoid the cost of a new windshield if possible. Maybe Inshould take it to a professional?
Any tips/comments/anecdotes/experience are appreciated. Thanks!

Everytime i’ve looked into it all i hear is that it can’t be done. Glass is so hard it takes ages, and is unlikely to even get the scratches if they’re more than a super light whiff across the surface.

Glass is very hard, you’ll have an incredibly difficult time polishing it clear, and if you do manage odds are you’ll have weird optical distortions since it won’t be the right contour on the outside. Depending how expensive a windshield is, it may be worth a shot but don’t get your hopes up.

I’ve looked into this a few times and I always seem to hear that “lensing” is a significant issue. Unless youre very precise with how much material you remove during polishing it ends up distorting your view.

It’s not hard, you just need some cerium oxide and a rayon pad, is a great combo for polishing glass.
Use quite a low speed setting and keep the machine moving otherwise you’ll create flat spots, another reason to keep it moving is glass doesn’t dissipate heat as well as car bodies and will crack or shatter quite easily.
Best route is to check your insurance policy as to whether it covers a broken windscreen, many do over here but not sure about over there.

I can check my insurance policy, but glass coverage here is often quite pricey, and I’m pretty sure I’m not covered.
The glass has a good-sized rock mark that probably can’t be repaired, so eventually it has to be replaced, I’m just trying to get as much life as possible out of it.
I'll look into your suggestion. You would do it with a regular orbital like paint repair?

I’m going to rewatch this video as well, see what I can learn.

A dual action either reciprocal or forced rotation would be my go to, a regular rotary unless used with extreme care is inviting problems. The trick is to keep the pad moving.
You can buy ceriglass from many places on the internet.
If you take the car to a respectable detailers, they should be able to do it for you for around $100-200.

Best thing I can recommend is to learn as much as you can, especially about products and techniques, because many products work differently from others.

No worries.
The d etailing world is a very large and varied place to be in with so many different types of products on the market, even ones that do the same thing may need to be applied differently, different curing times, etc... generally a mass of techniques. It can be crazy.
