Windscreen Scratches

[101RRS]

Since I have had my RRS I have had the wipers set on auto with quite a few dry runs happening when the sensor got a bug splat or something similar. This function needs to have an associated squirt of water to apply lubrication to the screen

At result I now have a moderately deep scratch which will not polish out - not all that obvious from the outside but quite obvious on the inside.

Any suggestions on how to get rid of this scratch - I have now turned the auto wiper function off.

Toothpaste, try the "whitening" type which has a mild abrasive. I used this recently on the 101 with great effect. I buffed it with my $20 chinese buffer - worked a treat. No good on deep scratches.

Toothpaste cleans the glass but had no impact on the scratch.

Any other suggestions - is there anyone I can take the car to, or is it there for good??

Thanks

Oh well, at least your window will have a ring of confidence.:angel:

Not sure about your area, but I would try a professional like Obrien's or Novus.

Couldn't believe a dry bug would scratch a windscreen:eek: , unless of course the bug had kidney stones

Cerium oxide (and water..) will eventually get it out.

Simplest way... here's a link to start with:-

A good idea is to make a similar depth scratch on some scrap glass... and practise on that.

On a sloping/vertical surface I found that a plasticene 'dam' under the working area both contained the mess...and allowed re-cycling.... But that was tooo many years ago and I don't know if the stuff still exists, or works as well as it used to. Or what I think it did....

For a more modern approach, have a look at this.

I suspect this system fills the scratch up to the level of the glass surface, rather than grinds the surrounds DOWN to the scratch-bottom. On reflection, I'd suggest this may be a better way, depending on the co$t of a windscreen and your insurance policy...

Maybe a grain of sand caught on the blade and scrapped across a dry screen when the auto system activated - I now have that switched off. The bug needs to hit the screen outside the wipe area where the sensor is.

Thanks for that - the scratch is deep enough to feel so maybe it needs to go to a professional.

That would be the best way...

Plan B is a replacement windscreen.
Plan C is fix it yourself.
Plan D is......:twisted:

Took the car around to a few windscreen places and all indicated that there was nothing can be done.

So options are live with it (not in the line of sight - just annoying) or try for a claim on the insurance policy.

Those with auto wipe function on their D3/RRS I would turn it off when it is not raining.

Are you sure that's what scratched it - ie did you actually see it happen? I can't imagine the wiper blade providing enough force to scratch the glass on a one or two-time pass over the window. Maybe if there was something stuck to the bottom of the blade and it consistently wiped over the glass?

Cheers,

Magically appeared one day - obviously a piece of sand or a very small piece of stone caught between the wiper blade and screen. It follows the arc of the wiper blade. I replaced the blades shortly after but there was nothing impeded in the old rubber.

Bugger, must be a deep scratch. Sounds like the automatic wipers should be programmed to give a squirt of water before they activate.:angel:

I can vouch for the damage that sand can do to a windscreen. I work on Fraser Island and manage a fleet of LC utes that are always less than 25-30 000kms old, and the state of the screens deteriorates incredibly rapidly from new.

I can only put this down to the sand that inevitably winds up under the wipers as these vehicles do not generally travel during the dusk/dawn period where bug strikes are more likely. And these vehicles are also rarely driven on sealed or dirt roads where rock strikes can cause damage.

There's a lot of merit to the idea of auto wipers but if I owned a vehicle with them I dare say the feature would be turned off 99% of the time.
