Windshield Protection Film
A layer for the glass.
ULTRAFIT WinCrest windshield protection film, installed in Prior Lake, MN: a clear layer on the outside of the windshield that absorbs gravel strikes and lowers the chance of a chip or crack in the glass.
One rock.
Three bills.
A chip that spreads into a crack does not end with the glass.
- The windshieldA new one, fitted.
- The calibrationCars with driver-assistance cameras (ADAS) need them calibrated again behind new glass.
- The timeTime without the car while the glass is replaced and the cameras recalibrated.
The film is a sacrificial layer: it absorbs the strike, so a small one is less likely to spread.
WinCrest EVO.
ULTRAFIT’s latest.
ULTRAFIT’s current WinCrest film: clear, and applied without a heat gun.
- Clear to look through
- ULTRAFIT says it is optically engineered for clarity comparable to bare glass, at night too, without rainbow effects, haze or glare.
- Protects against damage
- Gravel, road debris and sand hit the film first. It lowers the odds of a chip or crack; a hard enough strike can still break the glass.
- Cost-effective
- Fewer windshield replacements, and fewer of the camera recalibrations that come with them.
- Durable
- Scratch resistant, with a removal-type adhesive that comes off clean when it is time to replace it.

Keep it
clear.
- For the first 72 hours, while the film cures: no car wash, and keep the car out of extreme weather and off rough roads where you can.
- Clean with mild soap and a microfiber cloth; avoid ammonia-based or abrasive cleaners.
- Make sure the windshield and the wipers are wet before the wipers run, so they do not skip.
- Clean the wiper blades and the lower edge of the windshield regularly, and replace worn blades right away.
- Keep a pressure washer at least 1 m (3 ft) from the film; ULTRAFIT’s warranty excludes power-washer damage.
- In winter, do not use an ice scraper directly on the film.

answers.
Does it affect ADAS cameras, sensors or a head-up display?＋
ULTRAFIT states its windshield films are optically designed not to interfere with ADAS systems, including HUD, cameras and sensors, so functions such as lane-keeping assist and collision warning keep working after installation.
Do the wipers scratch the film?＋
The wipers themselves do not. Sand or gravel caught under a blade can scratch the film, and ULTRAFIT’s warranty treats wiper scratches as normal wear: keep the blades and the windshield clean, replace worn blades, and run the wipers only on a wet, clean windshield.
Is the film permanent?＋
No. It is a consumable layer that protects the glass for a period and is replaced over time; how long it lasts depends on driving conditions, climate and wiper use.
Does removing it leave residue or damage the glass?＋
No. ULTRAFIT says its removal-type adhesive comes off clean, without residue or damage to the glass, even after long use. Have it removed by a professional.
Can I install it myself?＋
ULTRAFIT does not recommend it: the film needs precise alignment, tension control and adhesive handling, and a poor installation can mean distortion, bubbles, lifting edges and a void warranty.
Will it stop every crack?＋
No film can promise that. ULTRAFIT’s installation guide says WinCrest significantly reduces the chance of breakage, but does not guarantee full protection against strong impacts.
Is it worth it on a work truck or a fleet?＋
ULTRAFIT points to buses, trucks and construction equipment, which see a lot of gravel, sand and bad weather: fewer windshield replacements and less downtime. Its warranty runs 6 months or 6,200 miles and excludes off-road and gravel-road driving.
