I also have a Touring Edition and one of the trim features is the chrome rings around the dash gauges. Just shortly after I bought my PT, a car wash had used some kind of cleaner on the dash and it made some spots on the chrome rings around the gauges. I should have made them fix it, or pay for the repairs, but I didn't. I ended up removing the cluster front, and the 3 chrome gauge ring comes off from the painted dash bezel. I couldn't get their "spots" off of the chrome, and I didn't want to buy a new ring assy, so I just ended up taking some very fine sandpaper and removing the chrome, it doesn't take much sanding.
You can see in this pic where the red arrow is it should be chrome, but now just black, and I don't even miss the chrome.
So if you find those rings kind of hard to mask off to keep the paint from getting inside the rings, you may want to do what I did. Unless you're also going to paint the inside of the rings, then no masking will be necessary.
