Nothing is more annoying than when this happens. We fixed one on our car just a few days after it happening... then 6 days later we got another one in a similar place to the first. Couldn't believe it!!
Haven't fixed that one yet but I think I've had another 4 or 5 hits since then, no cracks or chips from them though.
Oh, that had to be frustrating!
It was and I've never have a chip before... but in the last couple of months we've had so many hits to the windscreen.
