Make sure to get the decal flat and in the right position the first time because the decals are VERY sticky and there are no second chances ! For what it is worth, wet the area where the sticker is to be position with a solution of dish soap and water. Three or four drops of soap for a couple of cups of water (best applied with a spray bottle) Done with care and properly does offer a second chance - sometimes. I did manage to slide these vinyl stickers around a wee bit...
