Automotive accessory that keeps rear-view mirrors clear in rain and fog, improving sightlines for safer driving. Drivers gain confidence when reversing or changing lanes thanks to clearer reflections. Does KOMUNJ Car Mirror Film deliver reliable, long-lasting clarity on daily journeys?

⚡ At a Glance
  • Visibility Performance: Nano coating and PET layers disperse water and prevent dew, keeping reflections clear
  • Best for: Drivers who regularly face rain or fog and need consistent rear-view clarity
  • Not ideal for: Owners seeking exact custom-cut films for unusually shaped or oversized mirrors

Transparent PET film uses a nano coating and a three-layer structure to reduce fog and repel water. Self-adhesive installation comes with basic tools and is removable without leaving adhesive residue.


Clear vision in wet weather - with nano coating and PET material

Nano coating helps water droplets spread quickly across the surface, preventing dew condensation, while PET layers maintain high transmittance for an undistorted reflection. The three-layer arrangement combines two protective PET films with a nano-adhesive layer to keep the mirror surface protected.

Rear-view mirrors stay readable during rain and mist, making reversing and lane checks safer and less stressful.

Reduced glare and water build-up - with multi-layer waterproof construction

Two PET protective films sandwich a nano-adhesive layer that repels water and reduces surface tension, so droplets run off rather than cling. The construction also lowers diffuse glare from wet surfaces.

Fewer distracting reflections and reduced water accumulation keep sightlines dependable in wet or bright conditions.

Quick DIY fit and clean removal - thanks to self-adhesive design and included toolkit

Pre-applied adhesive and protective layers allow a peel-and-stick installation after cleaning with the supplied cloth, then smoothing with the scraper and peeling off the outer protective layer. High-quality adhesive is formulated to avoid leaving residue when removed.

Installation is straightforward with the provided tools, and removal leaves the mirror surface clean and undamaged.
