I removed the pin stripe on mine with some plastic scrapers desigined to remove stuff like that.
Now the pin strip has been on the car since 87 so it left a gluey residue behind on most spots.
I used a paint thinner to remove the glue, BEFORE YOU USE THE THINNER, test it on your paint. Some paint will rub off into the rag you use with the thinner, but not a noticable amount.
Finish up with a hard waxing on all removed spots, if your car is old and has been baking in the sun for a few years, there might be some color difference underneath the stripes to the color everywhere else.
But all in all, it makes your car look sportyer.
