I'm not talking about scratch gouges, just the old wiper scuff marks you see on most old cars and trucks. | | | | | Joined: Jun 2009 Posts: 2,201 Shop Shark | | Shop Shark Joined: Jun 2009 Posts: 2,201 | 1000 grit wet sand with dish soap & water.

What are your goals? Is it originality,or cost effectiveness?
I assume the glass you're referring to is in one of your trucks.
Bear in mind glass for ADs is relatively cheap,so it all depends on how much you value your own time and labor.
It can take considerable time and patience to polish glass and depending on how deep the scratches are will determine the final result.
You can reach a stage where you get distortion at the areas that are polished due to the amount of glass removed.
Laminated glass is by far the easiest to polish on account of its relative 'softness'.
I suppose as a 'glass guy' my choice would be obvious,but the final decision would ultimately be yours.

I can't tell you the exact grit of abrasive that was used but it was done in several steps with each step being a finer grit paper/polish. I can caution you to not concentrate just on a small area or you'll get a distortion like a fun house mirror effect from "cupping" the glass.

One guy says to use Cerium Oxide, make it into a paste with water. I believe this is the same thing that Eastwood sells. It costs about $8 on Ebay. | | | | | Joined: Mar 2008 Posts: 3,750 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 3,750 | Thanks everyone. One guy says to use Cerium Oxide, make it into a paste with water. Tip; Mask everything with sheets or covers other than the glass you're polishing. You'll see why when you start...if you're using an electric buff that is! It works well but can(will)be messy!
