Stone impact damage at the front of the vehicle

Hello, I drive a silver-coloured Phaeton 3.0 TDI Built 05/05, which has so far run 35,500 km. On the vehicle front there are countless small paint damage, which probably comes from stone strokes. Since I am not a slow driver (travel speed – where it is possible – 180 to 220 km/h, high BAB share), this problem is already known to me from previous cars. Only the damages of the Phaeton are much more extensive than before with many BMWs and Audis. What experiences do you have with the Lac kqualität and has anyone ever been able to enforce a repair of the stone impact damage on guarantee? Thank you for your answers! Greetings TJN
