I removed the stickers from my Jeep today, and put on the Tree stickers from ProTek. Love these bad boys. I bought the 8" ones. No words, just woods.
Heated up the factory stickers with a blow dryer, peeled em off, cleaned up the adhesive residue with some rubbing alcohol, then applied the trees. One of those quick & simple mods (like the stubby antenna) that really make a difference, IMO.
You can PM Jamey on the forum (ProTek) if you're looking for some of these. They come in several different colors. I believe there are other types of stickers available, as well.
