It all depends on how much you value your clear coat and/or hate scratches and swirls.
I try to keep my paint mint, and here is the process I recommend:
1. Heat is your friend. Heat up the emblems with a blow dryer or heat gun.
2. Use dental floss instead of fishing line. Softer material = less scratches.
3. You only have to get a start and then you can pull the emblem off. Don't use the floss more than you have to.
4. Goo-Gone is the best product to get the remaining glue off. But:
5. Make sure the surface is clean and free of sand/dirt before you start rubbing;
6. Use a microfiber towel rather than just a "clean rag".
Even if you follow all these steps, you will still see scratches/swirls when you're done, but they should be minimal. With a simple random orbiting buffer like the Porter Cable 7424 it will literally "buff right out"!
