With these coatings the dirt might not adhere to the vehicle quite as strongly, but part of that may be due to the clay bar treatment performed first, during the paint correction process. This will remove most of the irregular bonded contaminants on the surface, leaving it glassy smooth. I've read stories of these cars staying cleaner with coatings or some anti-static effects that repel dirt. I haven't experienced this with my MS, especially around the lift-gate/ rear license plate area. I'm sure others can also attest, it's a low pressure magnet for dust or dirty beads of rainwater that sweep up from under and around the vehicle. Fortunately it does rinse off pretty easily.
