How to Refinish Auto Windshieldsby Alibaster Smith
When auto windshields develop scratches or swirl marks, the only way to refinish the windshield is to polish the glass. By polishing the glass, you can remove the scratches, swirls, or other marks or embedded materials. However, you can't use just any polishing compound. You'll need a polish specifically made for smoothing out glass surfaces. Many companies sell glass polish, but if you stick with a trusted name in the auto detailing industry -- like Eastwood polish -- you can achieve predictable, consistent results.
Clean the glass you will be working on with soap and water. Then, dry the glass with a clean, lint-free towel.
Apply a liberal amount of glass polish to the surface of the glass where the scratch or swirl marks are.
Rub the buffer across the scratch without the power on. As you work the buffer across the scratched surface, turn the buffer on the lowest setting and gradually increase the orbital speed.
Work the polishing compound into the glass, but do not apply pressure to the buffer. Let the polish do the work. Stop when the scratches or swirl marks have disappeared.
Clean the surface of the glass with soap and water again and dry the area with a lint-free towel.
