long story sort, the maintenance company of my flat was/is doing some drilling, loads of dust they did not cover my car, instead they tried to wipe it after. At last that's what it looks like on the bonnet and the side of the car. Car is/was brand new Cupra 300 and it was mind condition. Need advice what to do? Full polish? and how much is that? also do I have any change to get this paid by the maintenance company?
