Will the trunk rust if it gets water inside?
2 Answers
Water inside the trunk can cause rust. Reasons for water ingress: Water usually enters the trunk due to damage to the trunk's sealing rubber strip. Methods to prevent rust: If water enters the trunk, first clean it thoroughly to prevent rusting of the metal parts inside. Then, replace the sealing rubber strip with a new one. Leak detection methods: Use a watering can to simulate rainwater flowing from the roof to locate the leak. Check if the trunk lid is deformed, if the surrounding rubber seals are intact, or enter the trunk, close the lid, and observe where light comes through, marking those spots. Water ingress handling methods: Drain the water as soon as possible. If there is water, drain it immediately. There is a rubber drain plug at the bottom of the spare tire compartment in the trunk—removing it will allow drainage. Open the trunk for ventilation. Remove the trunk liner and all items inside, then leave the trunk open for about an hour to prevent mold and rust.
Previously, my car's trunk had water leakage because the rubber sealing strip on the trunk lid was worn out, allowing rainwater and mud to seep in unnoticed. After a few days of accumulated water, the metal floor began to rust, with rust spots spreading from the corners. Eventually, even the hook parts corroded. The rusting process was quite rapid, especially in humid environments, and was accelerated by dust and debris mixing in. I also noticed mold growing inside the trunk, accompanied by a strong odor. Dealing with it required significant effort—first, completely removing the accumulated water, then thoroughly drying it with a hairdryer, and finally applying an anti-rust coating for repair. Now, I make it a habit to check the sealing strip before the rainy season and ensure the drainage holes are clear. If water does get in, it's crucial to wipe it dry immediately, as prolonged exposure can lead to rust spreading to the car's frame, compromising overall safety.
