WINDSHIELD PROTECTION FILM

Windshield Protection Film

Invisible armor for your windshield.

SunPro Windshield Protection Film is a self-healing, optically clear layer engineered to absorb stone chips and road debris before they become cracks — without distorting the driver’s view. It conforms naturally to curved glass with zero heat forming, for a cleaner install every time.

Inside The Film

Five layers. One job: protect the glass.

Every roll is engineered as a precision stack — from an impact-absorbing topcoat down to a glass-ready adhesive.

Why Windshield Protection Film

Real protection, zero distortion.

Engineered from a self-healing top coat and an elastic optical film, SunPro Windshield Protection Film absorbs impacts that would otherwise chip or crack an unprotected windshield — while staying virtually invisible to the driver.

Self-Healing Surface

Minor scuffs and swirl marks resolve on their own — accelerated with heat or steam — keeping the surface looking new. Verified with copper-brush testing.

Crystal-Clear Optics

90% visible light transmittance and less than 0.8% haze mean no distortion, glare, or haze in the driver’s line of sight, day or night.

Built for Curved Glass

The elastic optical film conforms naturally to curved windshields — no heat gun, no excessive stretching, and a faster, cleaner install.

Installer Reference

Application & care, simplified.

SunPro Windshield Protection Film is built for straightforward application and long-term performance. Keep these guidelines on hand for every install.

Storage

  • Recommended application temperature: 64–74°F
  • Recommended humidity range: 40–60% RH
  • Avoid extreme high or low temperatures and high humidity
  • Store the roll horizontally

Installation

  • Unroll and cut only what is needed; re-roll and tape any excess to maintain tension
  • Fully clean the glass surface of oils and debris before application
  • Pre-cut the bottom section if pattern-cutting is difficult
  • No heat gun needed — the film conforms naturally to curved glass; avoid overstretching
  • Use moderate squeegee pressure for quicker, cleaner water removal

Maintenance

  • Apply a dedicated top coat every 3–6 months to extend durability; avoid surfactant-based chemicals — washer fluid is safe
  • Use a joint-type wiper, and clear debris or ice before operating wipers
  • Avoid concentrating high-pressure washer spray on the film edges; high-temp steam helps activate the self-healing coating

Rework & Removal

  • Best performed at room temperature
  • Pull the film carefully to remove; a steamer is recommended in winter conditions
