Well it took a while to get around to this one.
I ordered stripes from vinylstriping.com they ran off 140 feet of striping for around $60 delivered which will probably do three Trilliums or just enough if you mess up really bad.
The color match for my 4500 was - vivid blue 1018
2" is probably close enough but I ordered 1 7/8" because that is what I measured on mine.
After removing the decals and glue I made guide lines using masking tape using the "ghosts" of the old stripes still visible on the
fiberglass.
The tricky part was going around the corners - had to pull hard to get them to conform to the bottom which narrows a bit. I might have had an easier time if I took of the top carrier film before getting to the corners.
The last photo shows new stripes against the old one still on the door.
