So i got my car back from autobody because they painted some panels on my black car. Well I washed it and I noticed on my rear trunk panel corner that the paint is rough and somewhat of a different color like a smokey dull color. Its rough when you touch it. You can see it at an angle def in daylight. Is that what overspray is? I tried rubbing alcohol pads 70% and that did nothing. Should i buy Meguiar's C-2100 Professional Detailing Clay, Aggressive? Do I need the aggressive? I really dont know what this is. This section is not even what they painted. How do I get that little area back to my clean black paint to match?
