thanks for your reply.
At this stage I am not sure that my policy does cover it.
The policy was initially on my Carlton GSi 3000 & I transferred it onto the Skyline.
When it was on the Carlton you had to opt in for windscreen cover & I do not think I chose to.
I'm checking out availability & costs on the screen.
It may even be that the best answer is to add in the windscreen cover on the policy & claim in a few months!!!
