They said they did could it be that im hitting something else and not the fender? But I doubt it if its something else, the wheels that I got is almost the exact diameter of the OEM wheel.

What's a good marker to put on the fender or tire so that I can actually see the marking if it happens again? Would rubbing the whole tire with armor all work? So if it rub again I will be able to see where it is actually rubbing. Thanks much guys.
