water does not turn rust color without metal to rust. and i think it should be warrantied, it shouldn't be my responsibility to fix the issue on a bumper that is only 8 months old, and its not only just the seams that is rusting, rust is coming thru on the tube as well,
Hey, I understand your frustration about this. How would they do the warranty repair? You would have to get the bumper back to them for repair. That would be quite costly I think.
