I just used fishing line and a bit of heat from a hair dryer. The KIA
badges are stuck on pretty good, so you're going to break the line quite a bit. Once off, a lot of glue will be stuck to the car. I sprayed the glue with WD-40. Let that sit about 10 minutes, then carefully pulled the big chunks of glue off with my fingers and thumb. Once most of the glue was off, I then used a cloth with a little bit of WD-40, on the cloth, to get the rest of the residue off. Then I washed it with some megueirs car soap, then I gave it a couple coats of wax, specifically I used the stage 1 and 2 mother's wax followed by a regular wax afterwards. Cleaned it up perfectly.
