The service manual is very vague on instructions on this. They don't even show or talk about that screw securing the strip at the very front. Other than protecting painted surfaces near by, they say (using some type of tool), start at the forward leading edge lifting/prying the trim away from its securing clips, an work your way back. They show it as 1 piece in the service manual, but it sure looks like 2 pieces are joined together on my car to make up the entire run. Whether its 1 or 2 pieces, it does say to start the re-install at the rear. It reads as thou there is a dedicated locator/positioning device (called a datum pin) on that rear most section. That has to be in the correct location during the install, in order to return the entire trim piece back to its original/correct position. I've never touched mine, so I'm not sure how easy or difficult it actually is to remove it.
I removed mine, primed and painted it and put it back on when I first bought my car and I didnt know crap about it back then. I think I posted what I did.... I know I have a bunch of pics in my google account. Not sure why I wouldnt have posted them in here.
