I am aware that the answer is: “Nothing!” Background of my question: With us towards the company a piece of road in length of approx. 500 with roll split was clapped full. We measured between 5 and 10cm, driving was hardly possible and even with 20km/h rims, bumpers and sleepers are now almost sand blasted. Teer stains I have up to the side panes that I almost 1x the woch e was allowed to wash with a tea-rent remover. My brother thinks that even stone-throwing foil doesn’t do much, it’s also very fast. Besides, I can’t have half the car tortured I had played with the idea of making Opti Coat on it, but that won’t really help in my case either?! At the moment it’s really a situation again, where I think about it, one cleans and cares, but everything is made a niece because of such actions. not even assert any claims, because it falls under general operating hazards… so at least my research on the Internet. Furthermore, this “construction site” will remain still at least until the end of next year, because it is always made into pieces
