Is there anything that can be done about small chips in my windshield?
Polishing Glass (Stage Two Surface Corrosion):
Once the glass surface has been washed and cleaned (detailers clay) any minor imperfections can be removed with an abrasive glass polish (Autoglym Car Class Polish or DP High Performance Glass Restorer) This thick citrus-based cream safely pulls contaminants out of the glass, including alkaline mineral deposits, and then smoothes out etched glass (http://www.autogeek.org)
Be aware the some imperfections cannot be removed and you may have to replace it. 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.
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.
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.
•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.
•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:
a) 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.
b) Janvil Scratch Remover (JV-326 / Glass Renew JV-325)
Alternative pads- these 4-inch ‘Metal Polishing Pads’ are made of course, 600 grit nylon (Scotchbrite®) and are designed for hard / rough surfaces like aluminium diamond plate, pitted aluminium, chrome, and glass. http://topoftheline.com
Note: Do not use an abrasive polish on Targa ‘glass’ tops as they are actually a plastic (Lexan) and an abrasive will remove the tint Suggested product- Plexus (BTI Chemicals Plexus® Glass Polish & Cleaner)
a) Glass Polishing Kit for Deep Scratches:
Most glass polishers contain Cerium Oxide an optical polishing compound (belonging to the group of elements known as rare earth) all necessary precautions should be used with regard to the dust produced, removes deep scratches from automotive glass and save the replacement costs. This abrasive system literally grinds away imperfections until scratches disappear, works best with a HS Rotary set at 1500-2000 RPM.
Warning- this system removes glass, maintain a wet surface and keep pad moving to avoid heat build-up an avoid causing optical distortion Eastwoods kit includes: self-adhering hook and loop pad, coarse, medium and fine abrasives. (Pro Glass Polishing Kit P/N # 40011 and instructions from Eastwood.com)

Anyone have any suggestions on this process? Anyone tried this?
I have some light pitting on my windshield and wanna try something like this to make it crystal clear again. But I've read a few scary stories about these polishes making "holigrams" on the glasses surface.
Patrick any suggestions?
