hey sparkle_motion, i understand your hesitation. i haven't put anything on my bumper, either. but i do have a bumper crop (
) of stickers on my rear windhield. I put them around the perimeter so they don't obstruct my view.
Does it come off easily?
it used to come off easy, now it's like seeing the pope.
i wouldn't try removing a sticker from your bumper. the paint under the sticker would look different from the paint on the rest of the bumper, which will have been exposed to sun that whole time, and be more faded. plus it could damage the paint.
i haven't tried taking any stickers off my window yet, but I've heard with a razor blade, some caution, and a LOT of patience, you can get them off.
