The History and Evolution of Windshield Chip Repair: From Shattered Glass to Smart Fixes

At Always Auto Glass, we pride ourselves on more than just fixing glass—we understand its history, science, and innovation. Ever wondered where windshield chip repair came from or how this remarkable process evolved? Let’s explore the fascinating journey from early windshield invention to the advanced repair techniques we use today.

🛠️ How It All Began: The First Safety Windshields

The story starts over a century ago. In 1903, French chemist Édouard Bénédictus accidentally discovered laminated safety glass. This innovation involved sandwiching a clear cellulose nitrate layer between glass panes, preventing dangerous shards from flying during impact.

By the 1920s, laminated windshields became standard in luxury vehicles. Companies like Rickenbacker and Ford (spearheaded by Henry Ford’s safety initiatives) introduced these safety features to the public, significantly improving driver safety (source).

🧪 The Shift From Replacement to Repair

Up until the early 1970s, any chip or crack in your windshield meant full replacement. That changed in 1972, when Dr. Frank Werner developed the first resin-injection system for windshield repair. His process restored both the clarity and strength of damaged glass—paving the way for modern repair over replacement.

Dr. Werner later co-founded Novus Glass, one of the first companies to bring resin-based windshield repair to the masses. You can read more about this breakthrough in Novus Glass's company history.

🔍 Inside the Technology: What Happens During a Windshield Chip Repair?

Here’s how professional repair services like ours at Always Auto Glass restore your windshield:

1. Inspection: We assess the type of damage (bullseye, star, combo, crack) and size.

2. Cleaning and Drilling: Using specialized tools, we clean the chip area and drill a small access point if needed.

3. Vacuum and Resin Injection: A vacuum removes air, and high-quality resin fills the chip or crack.

4. UV Curing: The resin is hardened using ultraviolet light, restoring integrity.

5. Polishing: A final polish ensures smoothness and clarity.

This procedure restores up to 90–95% of the windshield's optical clarity and strength. Our repair process is backed by industry best practices and years of expertise.

🔬 Edge Crack Repair: An Engineering Feat

One major advancement is the ability to repair edge cracks—once thought to be unrepairable. Ultra Bond, founded by Richard Campfield, developed a patented system to treat long and edge cracks that form near the stress zones of a windshield. Their studies show that repaired windshields can be just as strong—or even stronger—than replacements.

They also took on industry giants like Safelite to argue that many damaged windshields can and should be repaired rather than replaced (Ultra Bond vs. Safelite).

🧠 Fun Fact: Windshield Wipers Were Invented by a Woman

Before we had clean windshields, someone had to invent the wipers. That honor goes to Mary Anderson, who patented the first manual wiper blade in 1903. Later, Charlotte Bridgwood invented electric wipers in 1917—though her version wasn’t mass-produced. And in 1963, Robert Kearns invented intermittent wipers and later won lawsuits against major automakers for patent infringement. Read more about this in Smithsonian Magazine.
