just a word to the wise, I just did this for the 3rd time on my new civic, and it *can* damage your paint... I did it on my other 6th gen, both came right off, blowdryer, and plastic putty knife, before I just used a blowdryer and it came right off. this time I did it same as before, but this time when I took the emblem off, some of the paint decided to come with it even though the glue was almost gooey.. it wasn't major but a bit of the top coat of paint peeled off and looked pretty bad, not to mention the glue still stuck on there would not come off no matter what I used..
long story short I decided to put the emblems back on after painting them black, now they actually look better than without emblems so its all good, but just be aware that you should be careful or you can potentially peel off some paint with the glue
