Repair Scratches in Glass

Often the difference between just an “OK” restoration and one that is outstanding can be the condition of the glass. Fortunately, Eastwood has a solution in the form of the Pro Glass Polishing Kit for Deep Scratches and the standard Pro Glass Polishing Kit.

The Deep-Scratch Kit is designed to remove deep surface scratches from auto glass. Generally, if you can feel it with your fingernail, this kit is for you. (For “wiper haze” or general polishing, use the standard Pro Glass Polishing Kit.) Pitted glass or glass with a “sandblasted” appearance is usually beyond the ability of these kits, since the amount of glass needed to be removed would most certainly create a “wavy” surface on the glass, and optical distortion.

In terms of difficulty, this Deep-Scratch Kit ranks among our highest. I've always advised folks to “back into the damage”...that is, always use the mildest pad first, check for results, then go to the next aggressive pad if needed to remove the blemish. Once the initial blemish is removed, work back out using each successively milder pad, then finally, the polishing kit.

Please note:

  • You'll need plenty of water. It makes a real mess but the pads and glass MUST be kept wet at all times or permanent glass damage and rapid pad wear will occur.
  • It also takes a great deal of time, patience and repeated episodes of “dry it and check your work”. This is a job that realistically could take hours, even all day, to complete.
  • With the polishing pad, the felt needs to be soaked in water for about an hour prior to use, the powdered compound needs to be mixed with water to the consistency of toothpaste or cake icing, and it also needs to be kept wet. Yes, it does make one hell of a mess as well.
  • Lastly, never ever use a tool exceeding 2500 rpm or permanent glass damage will occur.
