This may have been asked & answered before, but couldn't find any search hits on the subject. So I apologize in advance if there is a thread on this subject matter. Last week I polished my car and noticed afterwards that the long plastic-type piece that runs under the doors is now a hazy white. There are other parts of the car with this same material as well. Anyone encounter this same issue? How did you restore it back to a nice luster black? I'm considering just wrapping these parts of the car, as they are quite bothersome to look at, if no solution is found. Thanks!
