During the recent race at rockingham, I noticed that the crack on my screen was growing larger slowly (and this may mean the expense of a new screen). After searching on the internet I located a local firm called ‘Glass Doctors’ you can see there website on this url http://www.glassdoctors.co.uk
David the director of the company was on duty and came out to see my car and the crack, he had no problem in stopping the crack (by drilling a hole at the end of the crack) and then filled the crack with some resin and after doing some other magic to the screen, cleaned it and I could not see without close inspection exactly where the crack was, and this should mean the screen will live for another day.
My only regret is I did not get a photo of the crack before and after.
