Side Emblems

I used a heat gun set on low (you can also use a hair dryer) then use a plastic scraper... you don't want to fawk up your paintjob..heat and anything metal scraping will do that....keep away from them.
 
I've used the fishing line 'saw' before without a heat gun and it works ok. Heat helps, though...

I think that I'd use a screwdriver (or whatever metal tool) as a last resort. Too easy to mess up and too hard to see just what's going on under there.

I have to remove emblems with the work I do with my business. The easiest and most effective way without doing damage is to use fish line or dental floss to saw or cut the tape. Once it is off you will have to pick (with your nails) the rest of the tape off. Clean area with alcohol and your done. You may have to double or triple up the fish line or floss so it doesn't break, but it works everytime, AS LONG AS IT ISN'T BOLTED ON! lol
 
heat gun lightly going around in circles. you'll be there a while waiting for it to get hot, but the longer it takes to get hot, the less damage you'll do to the paint.
