Not sure about the maintenance, but the color is beautiful.I'm very concerned about the care needed for the Matte finish. I've used Griot's spray- on car wash and speed shine for a few years with great results. These products can't be used on Matte paint. I have rarely had to do a regular car wash not being a daily driver. PPF on the front half of my 911 has also made these two products very workable. I can avoid bad weather except on out of town trips. Hoping to hear lots of experiences with Matte Paint. I didn't have time to research Matte Paint and expect to get a slot for the Edition 1.
