I just had Xpel ppf applied to my center stack and screen 3 days ago. It was $200 at a local, very reputable, detail shop. They have the ability to cut their own pieces...so they downloaded the pattern from Xpel and cut them out on site.
My installer told me not to clean it or wipe it for about a week, so it's still a little smudged up from the install. It also had some tiny moisture bubbles, which he said would evaporate and flatten out in a week or two. Parking it out in the sun helps. In 3 days, just about all them...except 3 tiny bubbles...have disappeared. If they don't go away, I'll go back and let him work them out.
All in all...it will probably be the best $200 I ever put in this vehicle. The edges are practically invisible, and I can tell from the feel that it will be much more durable than the piano black plastic finish. It has a slightly softer, tactile feel to it. I would definitely recommend it.
