A windshield repair kit will work just fine if the chip is no larger than a quarter. A high-quality DIY kit will stop a rock chip or crack from worsening but won't repair the damage. Experts employ similar methods to fix minor chips and cracks. You might wish to get the windshield replaced if the crack, bullseye, or star is squarely in your line of vision. Additionally, if your car is old, the windshield probably has to be replaced because it may also not withstand stress.
