Windshield repair involves squeezing resin into the ding or crack by a vacuum that seals out air and moisture. It is then exposed to UV light to dry the resin to a crystal clear finish. Scratches on the windshield are treated differently. A glass polishing kit is used to eliminate scratches by grinding the glass level to the bottom of the scratch to bring back glass opacity. The glass is then waxed to smooth perfection.
If done properly, windshield repair saves you money because it costs less than windshield replacement. Though most small blemishes like nicks, cracks, and scratches can be repaired, a replacement is recommended for long or spidered cracks that affect the whole windshield.

When doing a repair, there are several things to keep in mind. This is the reason why it is so much better to let the experienced hands of a windshield repair technician to do the job and not to do it yourself.
First, the repair should not be done in an open area exposed to direct sunlight or else the resin will harden too quickly and your repair won’t be as beautiful as can be. It is also very crucial to keep the damaged area clean of loose pieces of broken glass using a glass cleaner to pick them out and clean the surface.
Second, it requires delicate handling because even the tiniest speck of dust in the resin can affect the strength of the glue that aims to eliminate the blemish.
It requires drilling of tiny holes into the glass and uses special glazing techniques to make the scratches and cracks disappear from the naked eye. Only skillful, experienced hands of a windshield repair technician can do it quickly and efficiently. You might be surprised to learn that a car windshield is comprised of three layers — generally, two pieces of glass with a thin layer of polyvinyl butyral between them. Polyvinyl butyral, or “PVB,” is a sheet of resilient plastic film that essentially holds the glass pieces together. If the outer glass layer is struck by a rock or other debris, the glass might flex and chip or crack. A rock chip is the most common type of damage, and it can form a star shape, a radiating bull’s eye or a crack.
Watch Out – Chips Can Grow
Although a small chip in your windshield can seem minor, it will probably eventually form a crack. Temperature changes and bumpy roads are just some of the factors that can cause fatigue stress to the original damage and cause it to spread.
Stopping Cracks in Their Tracks
The science of crack repair has changed and evolved over the years, but the method is the same: to substitute the air within the crack or chip completely with acrylic resin. This process serves to prevent further damage, restore the structural integrity of the windshield and also improve visual clarity for the driver. Windshield repair is generally at least attempted before a windshield is replaced, especially if the damage is minor.
When It’s Time for a New Windshield
If a rock chip spreads to become a larger crack, windshield repair is less viable. A new windshield can cost depending upon the type of vehicle and replacement windshield required. Windshields bought from the original manufacturer tend to be much more expensive than aftermarket versions. Add-ons like sun coatings, heating elements, and antennae increase the cost even more.
Some Concerns and Considerations
When a windshield is replaced, make sure the installer gets as close to the original factory seal as possible. While it will never be quite the same, a good installer can come close. A quality seal is important for a variety of reasons, including preserving the structural integrity of the car. You may not give your car windshield much thought, but if you ever have to deal with windshield repair or replacement, now you’re up to speed on the basics.
