Well done Douglas. As someone who has insurance but dislikes claiming for anything, the price of a relacement screen, should it crack, would mean a definite claim. I hope that MMC, plays ball in the future and clarifies the cause of these cracks, so we at least understand and if posible take actions to prevent it occurring. As we will all end up paying with increased insurance premiums.
Aren't most windscreens only a minor/no excess and do not count against any no claims bonus? If so I would claim each time...
