Things You Didn’t Know You Could Fix With Nail Polish
Stop a Windshield Crack
It’s a temporary but helpful sealant. Want to stop that tiny crack from spreading across the windshield? Park your car in the shade and paint the crack on both sides of the glass. Then pull into direct sunlight to let it dry.
Again, it won’t repair the crack, but it will keep it from spreading long enough for you to get the windshield replaced.
