What caused this and how do I fix it?

This showed up during a recent car wash. I've use chem guys citrus and have for every wash I've done on this vehicle and it's currently 3 years old, so I don't think it's the wash. Any ideas what caused it or how to correct it? I've tried Mother's Back to Black with no success. Thanks for the help.

 

Looks like you got paint on your vehicle. Possible you ran over it or someone painting near your vehicle over sprayed.

 

Can you come Sunday? I may be able to machine buffing out. But i need to see this. Car wash may just put dressing to cover up oxidation. Sorry. I did not ask where you are. I hope it is not acid, if so, there is not much you can do, and you have to re-paint. Just need to see it to verify.

 

use a heat gun, try 1 spot on your mudflap first, make sure move the heat constantly. if your uncomfortable using heatgun use this.

I'm in the Destin, FL area. Thanks for the thoughts. I've tried the machine buffer and think it may just need a new paint layer. I'll try the Solution Finish and see what happens first.

 

Looks like what happens when you put degreaser on plastic/paint.
