Repair quickly. I had one that size and as soon as the temperatures dropped, it became a crack and went the full width of the bottom of my screen, in the space of about 5 seconds.

The round shape in the middle and the six main cracks can be filled. here are a multitude of smaller cracks between them which will also fill during the process.

Known in the trade as a combination repair.

I've something similar but smaller, local windscreen/repair company had a go at a repair and left it looking exactly the same. He definitely drilled and filled it with riding but nothing happened really. Can this be tackled again do you think or us it new screen time ?

@Glassman... a long-shot but could a broken glass fisheye lens on a front-facing 360 camera be improved at least by a repair? I took a stone-hit to mine, still works ok except the view is obscured by the cracks and a new OE one is nearly £550 before fitting!

Had a repair attempted on stonechip on the driver's side. It was much better, but you'd easily notice it every time you got into the car. Was happy for autoglass to call it a failed repair, and for me to pay the bigger excess for a new screen.

Rule of thumb is that a repair cannot be re-repaired. However, some repairs can.

If the 'break' hasn't been filled, and generally looks the same after the attempt as it did before, there is a chance of getting back into it. Re-repairs can be very straight forward in this instance but they are risky, especially if the break has been partially filled. The technique in this case would be to pop it open again, creating a chip within the chip.

The general standard of repair is very low as there are so many repairer who a) cannot be bothered, and b) don't know what a good repair looks like never mind know how to achieve one.

Not had any experience with them. Happy to take a look though.

I don’t really mind if the repair is visible as long as it’s safe no way do I want a new screen if it can be avoided.

I think it would help if you understood the difference between a good repair and what is safe, or not.

A good repair will be almost invisible.

A windscreen is a sandwich construction comprising of two layers of glass with a polyvinyl butyral layer between them. It is safe, and given that windscreens are now directly glazed to cars (bonded) they aren't just safe, they're quite tough. That said, try not to misinterpret any adverts you might hear and how a chipped windscreen is dangerous and might lead to really bad things happening in the event of a collision. The keyword in structural rigidity is rigidity, or stiffness (and it adds about 30%). Technically speaking the windscreen in this context is part of the 'structure' of the vehicle, but it doesn't act like a roll cage. It's like watching the doors on the back of a trailer and how they move. Take them off and fix a solid panel across the opening and there'll be no movement. Same principle.

Your windscreen is safe. But what you might be identifying as safe, or safe against is the difference.

Good luck.

It would be interesting to know the process. As I understand it, one national repairer will get you to sign a disclaimer which absolves them from any responsibility should the break crack. Another says to its customers that the repair isn't necessarily a cosmetic improvement which is total bullst.
