Just washed my car, and I found the following around both rear marker lights.
I'm not sure exactly what it is, but it didn't wash off. It feels smooth, it's on both sides of the vehicle, on the plastic bumper covers. Nothing above the marker on the metal. Car is a 2011 Camaro SS.
I'm not sure what to do with it, I've got a Dual Action Polisher. How do you suggest I start looking into this one?
