TPU Film vs U-Channel Guard
TPU film is nearly invisible and conforms to any curve, while a U-channel guard is visible but far tougher. Pick film when looks come first, U-channel when the door takes real hits.
Invisible vs armoured
Film disappears on the paint; U-channel adds a visible but protective lip.
Impact resistance
U-channel absorbs contact far better than thin film.
