nope, no parking under trees. That week, it was only in the garage and to and from the gym. Only once was it at work, but no trees at work. Its all buildings.
... and it appeared to only be rough due to the dust on the car that seemed like it hardened onto the surface???
I had a chance to check it out in the sun and no marring occured from me wiping it down after the wash with detail spray. I really layed on the detail spray though when i was wiping, just in case! I'll just have to wash the car sooner when it gets that dusty.
