There are many threads about paint protective film in the A6/A7 forums. There was a statement about over 100 threads but I couldn't locate it.
The film is worth it. When I checked the used Audi's at the dealership, all had multiple chips in the bumper cover. Many people have the entire hood and fenders covered.
As I've grown older, I've learned that pleasing everyone is impossible but pissing everyone off is a piece of cake
