They're held on with a 3m type of tape. Very stubborn stuff. Some of it was hard so I warmed it in the hot sun and used plastic chisel/scrapers to get most of it off, then used a goof-off type solvent to remove the residue. The paint under them doesn't look much different. For the pin-stripe, I tried several things, but the best thing for me was let it sit in the hot sun, then used all my finger nails! Then used the solvent to remove the adhesive. You can still see where the stripes were, as if the glue causes the paint to swell in those areas, but I like it better. I never cared for the pin-stripe. I think the car has such hard lines, that they don't need to be high-lighted. The solvent did flatten the sheen on the paint, so I had to buff those areas again.
