I removed vinyl decals (huge decals) off of a 1993 Ranger STX I owned years ago more than a year after I got it. Used a hair dryer and took my time. Went over the vehicle with a paint cleaner product to remove any residual adhesive and buffed it out. Easy Peasy. Did it on a cold day with clear skies and direct sunlight. Just take your time. A hair dryer unlike a heat gun won't harm the paint if held in place too long.
