I discovered rust on my 6 month old Nissan. no, this was not a stone chip or scratch gone awry... it started behind the "chrome" trunk strip; although apparently it is common to start behind the "chrome" Nissan emblem - and the problem involves many models. apparently the back side of the "chrome" pieces is not smooth and wears through the paint. my dealer was no stranger to the problem. I am NOT happy about having my trunk repainted- while it might match today, eventually it likely will not match.
