WPF – Product Information
Description
This product is an adhesive protective film designed to protect vehicles from impacts, such as stone chips, that may occur while driving. The elastic material used allows for easy application on curved glass surfaces without the need for heat forming. Additionally, the excellent top coating layer maintains visibility while providing outstanding slip and stain resistance.
Application
Exterior of the car’s front windshield.
Storage
- Recommended application temperature range: 64–74°F
- Recommended humidity range: 40–60% RH
- Avoid extreme high temperatures, low temperatures, and high humidity
- Store the roll horizontally
Installation Instruction
- Carefully unroll the film, cut the amount needed, and after use, roll it back up to maintain tension and store it with tape to secure it.
- Before application, it is essential to remove any foreign substances and oil film from the glass surface.
- If using a cutting program for pattern work is challenging, pre-cutting the bottom section will make application easier.
- This product naturally adheres to curved surfaces of glass, so using a heat gun is unnecessary, and excessive stretching should be avoided.
- Since quick drying can be achieved with appropriate pressure on the squeegee, avoid applying excessive pressure during water removal.
Maintenance Instruction
-
Coating Application
It is recommended to apply a dedicated coating on the film surface after installation. Depending on the environment, applying the coating every 3 to 6 months can enhance the durability of the product. Avoid using surfactant-containing chemicals other than the dedicated coating, as they may cause surface damage. Washer fluid use is acceptable. -
Wiper Operation
It is recommended to use a joint-type wiper rather than a straight or silicone rubber type. If dust or particles are present, they may cause scratches, so it is best to clean with water or a suitable cleanser before operating the wiper. In winter, ensure that ice on the windshield is removed before using the wipers. -
Car Wash
When using a high-pressure washer, avoid concentrating the spray on the edges, where peeling is a concern. High-temperature steam washing can help activate the self-healing properties of the top coating layer. -
Rework
It is generally preferable to work at room temperature. Carefully pull the film to remove it; in winter, using a steamer is recommended.
Warranty
- 1-Year limited warranty.
- Only applicable in the case of proper storage, handling, and use.
- Terms and conditions apply.
