I do not believe that there is any one piece that is best to remove before another. You need to get a trim removeal tool and slide it between the glass and the trim. I suggest placing a wash cloth or other protection under the tool to save your glass from scratches. Move the tool around until you find a clip they are every 6-8" or so. Get the tool to hook behind the clip and pull gently towards the center of the window. At the same time apply a little lifting pressure under the trim. This will unhook the trim from the clip. Continue this for every clip until the trim can be removed.

Check your repair area and fix as needed.

To reinstall the trim, have all of the clips in place. These are available new at most paint supply stores. They are inexpensive and usually justify replacement. The trim will need to be joined together as you go or at least before an entire piece is completly installed. They simply snap in place behind the clips. reinstall is usually pretty easy. Make sure you have a helping hand to keep that paint in good shape!

Good luck!
