Car wraps will not get scratched. More information about car wraps is as follows: 1. Rain Protection: Many car wraps claim to use nanotechnology or lotus leaf technology, where water droplets do not stick and simply slide off. In reality, most cannot achieve the advertised effect. It might work well for the first week after application, but the effect gradually diminishes over time. 2. Stain Resistance: This is similar to water resistance. Many promotional videos show dirty water being splashed onto the car, with the water flowing away without leaving stains. Like the first point, this effect is temporary and usually due to a hydrophobic coating on the outer layer of the wrap. This coating loses its effectiveness quickly after exposure to sun and rain, so expecting to never wash your car again is unrealistic. Moreover, this only applies to dirty water—dust, mud, and other contaminants generally have no protective effect. 3. Scratch Resistance: This might be the most appealing selling point. Many car wraps claim to resist scratches or even self-repair, which is also unrealistic. Consider the car body itself—from production to delivery, it undergoes numerous metalworking, stamping, and painting processes, with technical costs that small manufacturers often cannot afford. At best, these wraps can only prevent scratches from reaching the car's surface, acting like a phone case where removing the wrap reveals a pristine surface underneath. However, deep scratches or collision damage will still require repairs.

To be honest, as someone experienced in automotive detailing, I must warn you that using a blade to trim paint protection film absolutely carries the risk of scratches. This is because the blade tip needs to stay close to the car's surface for precise cutting, and any hand tremor or excessive pressure can directly damage the paint. I've seen many DIY enthusiasts who thought they were being careful end up with permanent scratches or even rust issues. The level of risk depends on skill, blade type, and environment—beginners are more prone to mistakes, and dull blades are more likely to snag. To avoid this, opt for rounded safety blades, keep the work area clean and dust-free, and practice cutting on scrap film first. It's best left to professionals who have the expertise and use laser or template aids to minimize scratch risks. While PPF is meant to protect your paint, improper application can backfire—spending a bit more for guaranteed results is worth the peace of mind.

As a car owner who just got PPF installed, I can share real experience: The risk of knife marks does exist. The professional shop I chose operated extremely steadily - the technician just lightly glided the blade over the film surface without touching the paint at all. But when my friend tried DIY installation at home, applying too much pressure left a visible mark that cost 600 yuan to polish out. The key is careful tool handling, especially when the film isn't properly adhered as it may shift and increase scratch risks. Avoid working in windy or poorly lit conditions, and wearing gloves prevents hand slippage. For DIY attempts, first mist the film surface to facilitate movement, then cut by gently pulling the blade parallel to the car body. While PPF mainly protects against scratches, the priority is not damaging the car - sometimes it's wiser to let professionals handle it.

From a safety perspective, using a blade during the car wrap installation process can indeed cause scratches. When the blade contacts the car's surface, any mistake may leave marks or deep scratches on the paint layer, affecting both aesthetics and structural protection. The main reasons include improper operation, a dull blade causing pulling, or dust interfering with smooth movement. I emphasize preventive measures: wear protective gloves to maintain stability, choose rounded-tip blades to reduce puncture risks, and keep the work area clean to minimize interference from debris. Although the film protects the car, the tools can be hazardous. Beginners should avoid high-risk scenarios and prioritize seeking professional help. Safety standards must not be overlooked to prevent additional damage.
