I didn’t know that if the rock basically put a hole in the windscreen that you basically have to replace the entire window. There isn’t a way that people can get the chip patched up and looking good again? I think it would be a shame to have to replace your windshield because of a 2mm hole in the glass.

I’m super disappointed that the edge of the windscreen is the one place that makes the whole thing weaker. My car is literally a month old and when driving down the road the other day a construction vehicle kicked up a rock that hit the edge of my window. I was hoping it would just be a quick repair. Hopefully I can find someone soon to repair it rather than replace it. Do I need to replace it if it is just a little dent on the edge of the window?

That’s really cool that there are ways to actually repair chips and dents in your glass. My car recently got a pretty nasty crack in the windshield from driving behind a semi-truck. I’m not sure if this method will work for a crack so big, so I might just take it to a service to be safe. Thanks for the guide!

I never knew you could repair glass like this. You can’t even see where it was in the video. Normally when I get a crack like this I just replace it, but no longer.

Thank you for sharing. I did not know you could repair a windshield like this. The video was most helpful. I have a small chip in my window just on the bottom right. It seems like it might be easier since it’s not in the direct line of sight. I will look into this.

They should call that first crack the spider. It looks like a spider was smashed into the window. I’m lucky that mine isn’t that big, but it is starting to spread. It looks like it could be an easy fix at the moment. How big of a chip and crack do you think they can fix?

I was driving on the freeway when a big truck’s tire kicked up a stone and it hit my windshield. It left a pretty considerable crack, and I don’t know what to do for it. I didn’t know that you could get tool kits! I’ll make sure my windshield is fixable first. Thanks for sharing!

Chipped windshields are the worst. I know that they can get worse and even start to crack if you do not repeat it soon. I did not know that the position of the crack or chip could influence whether you could repair it or replace it.
