Is the Trunk Sealed?

The trunk is in a sealed state. Here is relevant information about the car trunk: 1. Introduction: The car trunk is sealed because it uses sealing strips for sealing, which also have the function of preventing water intrusion. Similar to the sealing strips of a refrigerator, air is basically unable to escape from the trunk. 2. Functions: (1) The elastic net on the trunk can be used to secure fragile items. Almost every car's trunk is equipped with an elastic net. If there are fewer items in the trunk, placing fragile items can be troublesome as they may roll around. In such cases, the elastic net can be used to secure them. (2) The trunk partition can create a relatively hidden and safe space in the trunk, which is very practical. Generally, many cars do not come with this partition, but it can be installed later. Of course, it is more common in SUV models. The car manufacturer usually reserves the position for it, making installation convenient.
Speaking of trunk sealing issues, I've driven several cars and found that they're not completely airtight. My old car had rubber sealing strips mainly to prevent rainwater and dust from entering, but every time after rain, I could always see some damp marks in the corners. I know this is normal because trunks aren't designed like submarines, and manufacturers consider air circulation. Once on a long trip, my trunk leaked badly, and it turned out the sealing strip had aged and cracked. A small expense to replace it solved the problem. This taught me the importance of regularly cleaning the sealing strips—just wiping them with soapy water is enough to prevent dust buildup from damaging the seal. When using the trunk daily, I also make sure not to overload it, causing the door to not close tightly, which can affect the sealing. In short, trunk sealing is only partial protection, and keeping it clean can extend its lifespan.
From my observation, most car trunk designs aim to block external elements, but the sealing isn't perfect. My car uses rubber or silicone gaskets for cushioning and insulation, but they tend to deform or crack over time. Once when I took friends camping during heavy rain, a small amount of water leaked into the trunk due to loose connections between the seals and car body. This shows manufacturing processes affect sealing quality. I now test for leaks during car washes by spraying more water. I've also noticed significant sealing differences between brands - premium models often have thicker, better seals. Replacing seals is simple and cheap; my last DIY replacement cost just tens of RMB. Regular maintenance is crucial for keeping trunks dry and preventing mold from humidity. These practices help me better maintain my beloved car.
I've driven various cars, and trunk seals are generally not completely waterproof. My five-year-old compact car started to leak slightly after the seal wore out. Simply put, the trunk has rubber gaskets to block dust and rain, but they can't guarantee absolute watertightness. Common issues like water ingress during car washes occur, so I regularly check seal aging and deformation. Just keep it clean during maintenance.
