So I bought my first car a used 328is 5 months ago. The car had minor scratches at the back but not anywhere else. I washed the car about 2 weeks after I got it and everything looked fine. The second time I washed it after the water dried I noticed 2 rock/paint chips on the hood. Well everytime I have washed it since it seems like their is a new rock/paint chip on the hood and i'm almost 100% sure the majority of them haven't happened since I've owned the car. So my question is could the dealership have done some kind of waxing to make the chips look invisible, and over the time I have washed the car the wax has slowly came off? Cause I now have about 20 rock/paint chips on my hood and its really aggravating me and I don't have the money at the moment to get it repainted.
