Autoglass "attempted" to repair a 1cm ish chip on my windscreen, but it didn't work. He did say that it might not work cause its near the edge and the size, but I gave it a shot anyway. Paid a tiny bit and my insurance paid the rest for the attempted repair.
I can opt for a replacement screen for £70 excess?
Bit more info on my original thread
