scratched glass

[rozzerfodder]

Advice please,

I have noticed recently with the bright cold mornings that the arc swept by my wipers has left tiny tiny scratches on both the front and rear windscreens. Is there any way to polish to the screen to remove these?

I used AG glasspolish, it will remove tiny scratches. With a buffer I think you can remove even deeper scratches.

Could you tell me more about this AG Glasspolish ? Ie where to purchase, i have the same problem.

[Oivind]

I don't know where to buy it in Uk, perhaps Halfords... If you have deep scratches try to use a buffer while you apply it to the glass. It's called AutoGlym Glasspolish, and its slightly abrassive

Autoglym is stocked by most motorist shop's but supose Halfords have the biggest range,

You could also try Sonus glass polish gets all the ground in dirt off the screen.

If you ave a lot of dirt on youre windscreen you could also use a claybar. Works great But it don't work on scratches.

[VW_Bora]

Is the claybar the same one you use on the paint ?

[doggs]

use some Mer with a polisher this will remove smaller scratches and does a brilliant on the paintwork too!

You can get it from Halfords now £9/500ml I think

[Oivind]

Yes, use the same as you would use on the paint. I prefer to use a old one as the windows doesn't schratch as easy as the paint.

Polishing Glass:

Minor imperfections can be removed with an abrasive glass polish (Autoglym Car Class Polish) be aware the some imperfections cannot be removed and you may have to replace it. A replacement windscreen can sometimes be claimed on an insurance policy without loss of no-claim bonus, dependant upon coverage (check first with insurance company).

Some windscreen ‘glass’ is actually a plastic resin and will scratch easily, consult your dealer to find out what material was used for the OEM windshield.

Heat caused by abrasive polishing can soften and damage glass; foam pad and product used must minimize heat build-up. Since glass is a poor heat conductor any friction heat built up from polishing must be kept to a minimum by using sufficient product and regular misting of both the polishing pad and glass surface with water.

If you can catch your fingernail in the scratch 0.4 Mil (0 .004 –inch deep) you should consult a professional glass repair / replacement company.

Methodology:

•Clean glass to remove dirt, dust or road grime from surfaces (also see note 1)

•Apply clay (Magic Clay®) and lubricant solution (WooliteTM / Water 5:1) onto the glass surface (Do not apply to plastic as dulling may occur.)

•Apply a quarter (coin) size amount of Autoglym Car Glass Polish™ or Iz Einzette Glas Polish to a damp cutting / polishing foam pad (LC Orange or White) attached to a Porter Cable HS rotary polisher set at speed 1200 rpm.

•Apply to half of the windshield, polishing first in an up and down motion then in a left-to-right motion and then repeat on the other side, proceed to other glass surfaces.

•Go over the glass several times in each direction, glass will polish virtually residue free.

•Wipe off any residue, and polish with a clean dry 100% cotton Micro fibre cloth.

•Inspect glass for clarity and smoothness. Repeat if necessary.

•If the glass has PPG Industries Optech clear coating a more aggressive polish may be required

Alternative products / methods: Apply Zaino Z-12 with a damp cotton cloth to cool glass, apply to small sections at a time and allow to completely dry, buffing with a clean dry cotton towel. If there is any smearing or residue left just use Stoner’s Invisible Glass or any good quality glass cleaner to remove excess residue.

Note: Do not use an abrasive polish on ‘Targa ‘glass’ tops as they are actually Lexan and an abrasive will remove the tint
