A car’s windshield is responsible for the driver’s forward visibility, apart from keeping elements such as rain and snow away from the cabin.

But at some point in the car’s service life, a cracked or chipped windshield can happen, whether from unwanted physical impacts, sudden temperature shifts or simply from the material deteriorating over time.

2. Buy a windshield repair kit

Windshield repair kits can be purchased from auto supply stores. You can also ask around about shops that offer professional repair services, as they may have stocks that they can sell you.

These repair kits come in a variety of brands, and while they entail different procedures as to their use, the principle is still the same. Done properly, a windshield repair kit can yield excellent results, with the damage practically imperceptible to all but the most meticulous observers.

3. Start dry

Before you begin, make sure the surface is completely dry, with the windshield as close as possible to room temperature; this means that the procedure may need to be performed indoors or in a shaded area to protect against sun and rain.

If the glass is still wet, use a hairdryer to remove the moisture. Avoid using window cleaners or detergents that can leave residue on the surface of the glass. Acetone or lighter fluid can be used as alternatives, as long as you’re careful in using them since the excess can dribble down the window glass and peel the paint.

4. Removing the chips and cracks

The windshield repair kit usually comes with a syringe and adhesive for the application process. Peel off the backing film from the side of the precut adhesive strip, then apply it on the windshield, making sure it is centered over the crack or chip. Polish it using a dull or blunt object.

Proceed to peel off the rest of the film. Adjust the plastic adapter for it to fit vertically or as close as possible, then attach it to the film and polish again.

Pull the cap from the syringe, keep the pointy end up so that the adhesive doesn’t drip on the wrong part of the car. Connect the adapter to the syringe. Steady the syringe using one hand, while pulling the syringe plunger back as far as it can go.

Grasp the handle in the same position for one full minute, which will create a vacuum in the syringe and the crack. While still holding the vacuum, the air from the crack will bubble up across the syringe’s adhesive, and the adhesive will creep down in the direction of the chip and the glass.

Once done, you can now remove the adapter, syringe and adhesive sheet. You might notice some adhesive film left on the glass surface, but this can be easily removed using a paper towel dampened with alcohol.

However, you should leave a bit of adhesive undisturbed exactly above the chip or crack for some time until the glass is restored.

Wait until the adhesive hardens or cures, then take a sharp single-edged razor blade to shave off the excess. If the blade is sharp enough, the adhesive can be removed in a single pass. Be careful in polishing the adhesive patch to avoid making a mess.

5. Reminder

Not all windshield cracks or chips can be repaired by the DIY repair kit. The kit helps in sealing the chip or crack against outside elements, but there might be some visible flaws after the procedure. It can also reduce the possibility of the chip or crack spreading further across the surface of the glass.

Longer cracks, however, can’t be fixed. Same thing with spider cracks that don’t have air pockets, long cracks, and surface scratches. In such instances, you may need to turn to professional glass services or have your windshield replaced altogether.

Remember to avoid the following when repairing the windshield:

  • Relying on adhesive tape to patch a crack
  • Using superglue as a permanent solution
  • Painting over the damage with colorless nail polish
  • Falling for unsolicited scams that tell you to replace your windshield despite having no visible damage

When you notice a crack or chip in the windshield, have the damage fixed as soon as possible. Both for your safety and those of other road users.
