Hi all one of my delightful children has decided to drag something across the screen or my iPad across something. Either way it has resulted in a scratch pretty much corner to corner. Has anyone had any experience with polishing a scratch out or replacing the glass. It is not to deep in most places there is a couple of sections of the line where it is fairly deep. Obviously we are talking fractions of a mm here. The scratch s not effecting the performance but you can see it on light coloured screens. Any help or advice would be appreciated. Thanking you in anticipation.
