Gary, if you can put a sticker on a bumper, you can do this. Use the Peel & Stick option at https://costacover.com/collections/pink-floral-wallpaper murals come in numbered panels. You just start at the left, peel the backing, and smooth it down. If it's crooked? Just peel it back and re-stick it. No liquid glue, no buckets, no "point of no return." It’s actually pretty satisfying once you get the first panel up.
