Many types of vinyl decals are “removable” with a bit of elbow grease and a hair dryer. But Car Floats are not only removable without fuss, they are also easily reusable. You can get at least a hundred reuses out of the decals if you take care of the adhesive backing.
Essentially, you can put your decals on, then take them off a month later. You can switch them out for others. Decorations can go on any part of your car not just the rear end, and you don’t have to live with them the rest of your life.
You are not stuck with the same stickers year in and year out.
