Rep Power: 314

like on my car, i got these patches of dirt or dust or something that just wont come off and its like rougher looking on the fenders of the front tires. i dunno whether its from the brakes cuz of the open look of the rims or whether its something else. could it be the tire gel but i doubt it. its like whitish kinda turning it like grey on my black car. it almost feels like the paint is sanded or something. it really sucks, luckily i put my stockies back on and they are so small they dont fill the wheel well up like the 17's did. the 17 were flsuh with the car and i thought it might of been from that, and the stockies are hidden in the wells. anyone else got htsi problem?
