  • Question
    How do I fix an improper repair on a windshield crack?

    If bigger than a quarter in diameter you're supposed to take it to a shop for replacement. I've tried the crack repair stuff before on longer cracks, and used some at each end to hopefully stop the spreading. It didn't last too long for me.
  • Question
    My car windshield got a crack on my way to work by a truck loaded with sand and stones; the stone fell on my window and it cracked. How can I remove it (an easier and cheaper way)?

    If it's bigger than a quarter, you have to get it replaced, because the "filler" stuff doesn't usually work, and it usually spreads too. If smaller in diameter than a quarter, there are some kits at auto parts stores, Amazon, even Walmart had one a while back. It takes a try or two to get it right if you've never done these before, but you can do it.

Tips

  • Do the hairline crack repair as soon as you see it. The sooner you repair it, the better the results of the repair will be.
  • Even though the repair kit is meant for windshields, it will work just as well on car windows as the glass is the same.
  • Do the repair on a sunny day if you plan to do it outside. This allows the resin to dry faster and better.

Warnings

  • Professional resin injection methods usually provide better results than a do-it-yourself kit.
  • If the crack on your window is longer than 3 inches (7.6 cm) then a windshield repair kit will likely not work for you. In this case, it is best to contact a professional.
