Servus, when driving this morning I ground a metal edge of a transport. My question is now, because I don’t know myself with a car, if I should treat the following paint damage and if so, what would be my best possibilities. I have to say, a damage to the car rather less bothers me, but I have to remember that the fender would then start to rust? The car is a Polo type 9N3. I’ll hang pictures. How much would you estimate the damage? On the transporter we could not detect any damage this morning, as said it was also a bare metal part that I sanded. Thank you for your help!
