1. This is not your problem. You didn’t cause this problem. 2. Go above the dealer if any argument over who is responsible. 3. People working at the factory paint shop will know the details of how this happened after one look at your photo. They will have seen this flaw before, and they will not be happy about seeing it again. Not only because the flaw escaped detection before leaving the factory, but also because they have yet to put a permanent stop to what caused this to occur. Whatever the cause, it remains a problem. The person paid to permanently solve this problem has failed to do so. The people and system in quality control failed to detect this problem. In fact, this type of stunningly visual problem with the paint could be detected with technology, not the human eye/hand inspection. All around failure. Unacceptable from any auto manufacturer, but especially the likes of Porsche.
