I'm having a big (in Autopian terms) problem with the trunk on my A6. I recently worked on a large woodworking project in my garage and had to park my Audi outside for several months. During that time it was mostly covered and rarely driven. There was frequent snow, rain, and freezing temperatures, so I often found that the car cover got stuck to the car. Recently I noticed that the back of the trunk and the door handle surrounds appear to be extremely scratched. No where else on the car is the paint looking like this. I'm trying to figure out what it could be. It's like a fine spider-webbing running horizontally along the width of the trunk (same thing on the door handles). I took some pictures, but I may need more to fully show the damage. I have no idea if the weather could have caused it or what. Any thoughts? Thanks in advance.
