Hey guys! Hope I'm posting in the correct place here. I put the sharkfin antenna from visual garage on my car about 2 weeks ago and put a coat of Meguiar's NXT tech wax on it. It looked great. Today I was washing my car like I do every week and notice some black spots on my sharkfin. If you run your fingernail over the sharkfin you can feel the dark spots. I tried to rub them off with some quick detail spray with no luck. I could find these spot no where else on my 3 month old 07 car. Here are some pics.
Anybody have any idea what this could be? I polish and wax my own cars, but I'm not sure what this is, which IMO is the first step to repairing any paint problem.
I emailed visual garage, but want to see what you guys think so they don't give me some BS answer.
