New windscreen please quarry lorry threw a rock at my car 4weeks ago and hit the black part of the window where the window wiper is.... Went to wash my car tonight and i had the wipers up.... The hose got caught in the wiper and slammed down on the window resulting in a crack the lenght of the windscreen iv a wedding in sligo on saturday and iv to drive it! Could it smash? You cant feel it from the inside and i only just renewed my insurance thinking id cover but appears i dont..... how hard is it going to hurt my pocket and will it hold up until next week?
