Here's some ideas presented in the past from a variety of sources.
Removing stock tape
What's the best way to remove it without damaging the paint job ???
1. Carefully peel it off, then use mineral spirits on a cloth (old t-shirt works well) to remove any glue residue.
2. Use automotive adhesive remover from an auto paint store. I think it's a 3M product. The best stuff I've used for tape, decals, etc., has not harmed any paint I've used it on.
3. Use a blow dryer to heat it up. Glue residue came off with alcohol.
4. Spray WD40 under one corner and work it off slowly.
5. The hair dryer method worked well.
