Hi guys!

wonder if anyone had tried polishing their windscreen? I've got many wiper scratches/chips and a couple of bigger stone chips but nothing major(2mm if that)

wonder if it's worth attempting to polish them out ? or glaze them over with something?

anyone has any experience?

I don't think insurance will replace it because it doesn't have any major chips.

Thanks
 
I've had a scratched windscreen for years now. My research always falls down to using jewellers rouge kits but there is a lot of risk of distorting the view etc. It's also meant to be hard work as you could imagine with glass.

I've not entertained asking the insurance company, in case they say no, hoping the silly amount of things that hit my windscreen eventually crack it so it's a clear cut claim... however it seems Civic windscreens are seemingly bulletproof.
 
Fairly certain it will be too hard a surface to use polish on. The abrasives will simply break down just removing any stubborn marks.
 
You can claim on your insurance if say it's effecting your view. I did just that when the sun was shining it was hard to see clearly. £70 new windscreen.

I would always try to keep the factory screen in place and repair for as long as I could. IME windscreen fitters are no better than Kwik Fit and will happily ruin your car and cause whistles, leaks, and other rubbish.

At this point you complain to the company doing the fitting and make it clear that you will continue to get call outs at their expense for life, because the job is covered under a lifetime warranty for as long as you still own the vehicle.

So it's in their best interest to fit an OEM windscreen and do the job right. That's how you end up with an OEM windscreen and the job done right.
 
I got mine replaced last year through Autoglass.

When selecting my date online, I literally wrote in the notes section "please can I have a genuine BMW screen". I didn't expect them to even look at it let alone honour it, but low and behold the guy turned up with a genuine BMW windscreen!
 
And yes, glass is far to hard to polish. The polishes you do get will remove contaminants but won't even come close to removing decent scratches or chips
 
that's annoying! I've heard some horror stories about z4 windscreen replacement(guess the same with most modern cars) like auto wipers not working, leaking, wind noise, not fitting rubbers etc.

Think I'm going to have to try and deal with it by the sounds of it.
 
I have some massive scratches on mine. I blame previous owners not changing wipers.

I have been tempted to call autoglass and start a claim off for a replacement but keep forgetting.

I think that'll be the case with mine too, when I got it the wipers were SCREAMING. First thing I replaced on the car.
 
You can't really remove anything more than very light surface scratches, ones you can't even feel. If you try to polish them out you will end up with an un-even surface.

Also windscreens are laminated so your actually polishing plastic not glass.

The surface layer is normally glass.
 
CarPro CeriGlass via a rayon polshing pad on a machine, preferably rotary is the best you can do, but won't remove anything but the slightest of scratches really.

1. Grab a stone from nearby
2. Put stone on windscreen
3. Hit stone with hammer
4. Call autoglass / or insurance company or whatever it is you need to do
5. Profitzz

Lol the plastic is in the middle not on the outside.

This.

The glass is sandwiched between two sheets of laminate and I imagine anything used to reduce the thickness of the outer laminate would be viewed as compromising its integrity.

Just get a new windscreen and make sure it's fitted properly.

Totally incorrect information, as stated already the plastic is between 2 panes of glass.
