I got a crack in my front windshield right behind my rearview mirror and it's growing slowly. I don't really feel like buying a new windshield at the moment is there a way I can squeeze some more time out of this on while the crack isn't in my view. I was thinking about drilling a hole at the end of the crack then making a superglue plug or something?

Better fix that crack now before it goes all the way around the world and we have a second moon...

Dont drive the car

Maybe epoxying the crack?

There should be no deductable on windshield replacement...your insurance will cover 100% of the cost...or at least that is the case here and in every other state I am familar with. A phone call to your agent or company hot line or a web search / inquiry will let you know for sure. And no, you may drive around with the crack for years, but eventually it will enlarge and no way to stop it.

I had a small rock chip and a crack that started to get longer in two places. Went to a chip repair place and he put a small hole on the end of the cracks and drilled and filled the area of the chip. It stopped it. Can just barely see the crack and not getting any longer.

I have all the professional equipment for glass repair and have been using it about 8 years .
What I’ve found is that stars under 40 mm can be repaired 100 % and are invisible .

Cracks 4" and under on the other hand need to have the ends drilled as you plan. What I do is drill a 1/64 hole a mm or 2 away from the end of the crack and then tap the glass to drive the crack into the drilled holes . Then you can buy the consumer grade repair kit at an automotive store, and follow the directions .

It wont be optically perfect , but since its out of eye line that wont matter .

Edited to add

Cracks over 4" tend to keep spreading right through the drilled holes because
They weaken the glass below the stress threshold imposed by the body flex .

Yes they use a kind of epoxy to fill the crack if it's not too big. Most insurance will pay for this for free.

Get a new windshield.

I went to an auto parts store and purchase a windshield repair kit. It's been a couple of years ago, I don't remember the exact cost. Around $10.00.

The procedure was: 1) fill the crack / ding with polymer; 2) place a suction cap over the polymer filled ding; 3) use a syringe to suck the air OUT of the suction cap; 4) let the polymer set.

Can you see the ding? Yes. Has it "spidered" or enlarged at all? No. Am I satisfied? Yes, very much. Not counting the trip to the store, it was $10.00 and 15 minutes, plus "set" time. I get my car washed routinely, no problems to date. My car is garaged 90% of the time, though.

I've taken Super Glue and put it small cracks. That stops them. You need to use a hair dryer to make sure all moisture is out of the crack first.
If the crack is really long, more than a few inches, you're out of luck.

I have found that you can have it fixed for about $15 or so, OR pay $150 and just get a new one installed.
I'd try the remedies on this board first, and if that doesn't fix it, then just buy a new windshield.
