Is it the vinyl type of sticker or a decal? If it's the vinyl it should peel right off once you get it warm. If it's the decal type you going to need something else, the debadging how to won't work. They have a product for removing bumper stickers from cars but you might want to test it on a spot out of sight to make sure it won't harm the paint. Or you may want to ask at the auto parts store they may have an idea or know of a product, surely you're not the only one in this world who wanted to remove the ugly dealer sticker ( you may even ask at a dealership to see what they use to remove them).
Whichever, once it's gone you'll want to put on a good coat of wax to clean and protect it.
Put Goo-Gone along the egde of a credit card and slide it slowly under the edge of the emblem/sticker/decal, slowly moving credit card back and forth while pushing the card, til it comes up. Or just do it how we did at the dealership, slide fishing line under it.
I was waiting for someone to say goo gone and I really thought that I was goign to get all the way to the bottom and not see it.. phew.. thanks focusonthis! Yeah, I found that goo gone worked real well.. give it a shot.. nothing to lose.
