If it's not directly in your field of view, I think glass repair companies can fill it for you. They just can't let it distort your view. I would assume the U.S. has similar places to what we have in Canada. I don't know about the UK for you though Jeremy.
I got a surface nick on windshield and went to the glass people to see what they could do about it. They told me that it was just a small nick and they would have to enlarge it jus to get their polymer fill in it. I am just going to live with it for now even though it is right in front of me all the time. wintertime in Pennsylvania has too many rocks on the road.
Thanks all for the feedback. I guess I was wondering if there is a DIY product. Like jb I'll just live with it - fortunately it's on the passenger side. radred, know what you mean about the roads in the Keystone State, I grew up there.
I only have a previous-generation Roadster but it has the new 'pinch-tab' wiper attchment that BMW seems to use on all its newer cars, and so I presume including the F56. While fitting new blades, I knocked the lifted passenger wiper arm down onto the screen - and when it doesn't have a wiper fitted, the arm has two sharp points that contact the screen, one of which caused a little star crack. It can't be more than 5mm (3/16") diameter and or course is under the parked wiper, so I'm leaving it, but those with higher standards than me might like to watch out for this poor piece of design.
