i removed all emblems from the back of my civic with a hair dryer, GO-Gone, and a Credit Card. It'll work, but it takes time. Also be prepared to remove excess glue after you get the dealer sticker and the emblems off. BTW: you'll be able to see where the emblem was, but after a few good rains and baking in the sun, it'll go away. I want to remove my H emblem.... but worried about fillin in the holes...

 

I removed mine with heat, then bumper sticker remover and 10 minuits with a rag and pickin with my finger nail....once all the residue is off< i polished the spot with GT88 and there was absolutly no sign of the badges ever being there...I also rewaxed the whole trunk lid afterward....
