Removed Hyundai logo, Tiburon lettering and GT V6 in about 5 minutes using a metal spoon and WD40. I promise they are the best combination. Metal spoon doesn't scratch or dent, just put under the edge and use your thumb to pry it off. Easy. Then spray generously with WD40 and rub off residue with a soft towel. Doesn't take off clear coat at all.
I used 12lb fishing line and it took about 40 seconds for the "Tiburon" because of all the places it got temporarily caught, and about 10 for the rear H. Getting the goo off took another 15 minutes of elbow grease!
