My car is now coated with CPG CeramicPro. No significant improvement of the paint as I see it. Maybe a little bit more durable, but any use of polishing paper (after use of vax) or chamois leather (after gentle handwash) still makes small scratches /swivels. Totally unacceptable! BMW's Tanzanite blue metallic appears to be totally unsuitable as car paint. I'm just more frustrated than before.
