Do I need to cut holes for radar on the car's invisible film?

No, you do not need to cut holes for radar on the car's invisible film. More relevant information is as follows: 1. Function: Automotive invisible film has advantages such as improving the gloss of the car body, protecting against acid rain corrosion, oxidation resistance, scratch resistance, and elastic self-repair. 2. Features: The invisible film has the following characteristics: excellent extensibility, super tensile strength, and ideal conformity on any curved surface. It offers yellowing resistance for over 3 years and aging resistance for more than 5 years. Crystal-clear transparency allows it to blend seamlessly with the original car paint, without affecting the car's original color, and can enhance the gloss of the paint by 5%-20%. It can resist damage to the paint surface caused by petroleum, grease, weak alkalis, gravel, acid rain, etc.
When installing a paint protection film, special attention must be paid to the radar positions—holes must be cut out. Radar sensors operate by reflecting radio waves, and covering them with film can weaken signals, causing false alarms or malfunctions. Once, I handled a customer complaint about incessant reverse radar beeping, and upon inspection, it turned out to be interference from an uncut film. This is especially critical for parking radars and adaptive cruise control radars—even slightly thicker material can cause issues. The solution is simple: locate radar points before installation and use professional tools to cut small holes, ensuring aesthetics aren’t compromised. Modern car radars are highly sensitive, and with proper holes, daily use remains safe and reliable. Ignoring this can pose significant safety risks, potentially leading to accidents or costly repairs. Always consult a technician before film application to ensure both paint protection and radar functionality are maintained.
My personal experience with applying an invisible car wrap taught me that it's best to cut a small hole at the radar area. Last time after my car was wrapped, the radar kept giving false alarms, almost causing me to misjudge while parking. Consulting an expert revealed that the wrap material can block signals. The hole-cutting process was simple—the technician used a laser for precise positioning, leaving almost no visible trace. Not cutting the hole can lead to hazards like reverse parking failure or emergency brake malfunction, compromising driving safety. This is especially prone to happen in rainy or snowy conditions—a friend of mine had a similar experience, which was a profound lesson. Looking back now, spending a bit more to have the hole cut is absolutely worth it, ensuring the vehicle's normal operation and long-term durability.
