Drove away from the dealership yesterday lunchtime in my new car and within 60 mins I was glaring at my new stone chip. Ironically, it was kicked up by a Honda Civic, just like the car I had part exchanged for the Audi. I phoned Autoglass and they told me that unless the strike was larger than 4mm, there was nothing they could do. ****** typical, as mine is about 3mm but the ripple effect has blown a 10mm hole beneath the surface.
