I don't think this is burning.... more staining, but I could be wrong. Of course, white shows it the worst. I've been able to remove it with rubbing compound, which is why I am inclined to think it is staining and not burning.

I've seen guys put metal bezels around the exhaust that extend a few inches out, riveted in place. I always assumed this was for heat. But looking at the size and area of the staining on my bumper, the metal plate bezel would have to be pretty big and I think it would look like crap.

Is there any magic solution to this.... something I could put on here that could be painted or coated white to match the car, yet be easily wiped down and restored back to white after it was stained with exhaust?
