It’s true. The letter is smaller than I thought and decal vinyl material might not stick well because back area of ioniq5 is the most dirty area.It looks very nice!
From my experience as a former owner of car wrap business, these cut decals will not last long. They have UV protection, so no worry with sun damage. However, if the car is washed with high pressure hose (either at home or car wash), they will peel off over time, because the surface area is very small and the base material is plastic, not metal/paint.
