Taking off old decals or registration stickers can be easy, but putting them on and getting the in just the right place is not.
Try spraying the area with Windex first, then slap on the decal or sticker. You can move it around very easy until in just the right spot.
Wipe excess away with towel, wait 20 minutes and you are good to go.
Had a good friend show me this the other day, though it was rather Smart.
It works on your motor cowl also.
