Solution for rusty sunroof on Tiggo 3 is to remove the rust at a vehicle repair shop. Reasons for sunroof rust: The most common rust issue with sunroofs is rust on the sunroof rails. Due to prolonged vehicle use, the rails, being made of iron, may rust even though they were coated with anti-rust paint during manufacturing. Over time, the paint may peel off, leading to rust on the sunroof rails. If the rust on the rails is not severe, lubricating oil can be applied. If the rust is severe, the sunroof rails need to be replaced. Automotive Sunroof: Automotive sunroofs are installed on the roof and effectively promote air circulation inside the vehicle, allowing fresh air to enter. Additionally, sunroofs can provide a broader view and meet the needs of mobile photography and videography. Sunroofs can be broadly categorized into: sliding-out type, built-in type, built-in flip-up type, panoramic type, and curtain type, mainly installed on commercial SUVs, sedans, and other vehicle models.

When my Tiggo 3's sunroof rusted, I first cleaned off the rust by washing the surface with water and a soft cloth, then applied anti-rust paint, as the rust was mostly caused by aging seals or rainwater seepage. This has made me develop a habit: checking the sunroof drainage holes for blockages every month, lubricating the tracks with silicone oil to prevent rust, and remembering to open the window to air it out after washing the car to reduce moisture. I also found that prolonged exposure to rain and snow on the roof accelerates corrosion, so I bought a car cover for rain protection—worth the hundred bucks or so. If the rust spots are severe, it's best to go to the 4S store for sanding or replacement; don't skimp on this to avoid leaks damaging the interior. Remember, regular maintenance, including the sunroof, can prevent this issue. They always say rust may seem minor but affects safety—early treatment saves hassle.

To address sunroof rust issues, it's best to start from the source: inspect the sealing strips for cracks or deformities, as moisture can infiltrate and corrode the metal from these points. When cleaning, use fine sandpaper to remove loose rust and then apply rust inhibitor, ensuring an even coating. For daily maintenance, it's recommended to clean the tracks weekly and apply grease to prevent friction damage to the waterproof layer. Additionally, keep the drainage holes clear to avoid water accumulation. Unrepaired rust can spread to the roof structure, posing significant hidden dangers. For safety, visit a professional shop to measure humidity levels and replace damaged parts. When parking, choose a garage or shaded area to minimize exposure to sun and rain, thereby extending the sunroof's lifespan. Safety comes first—don't overlook this small detail.

I encountered rust on the Tiggo 3 sunroof, which I fixed with rust remover spray—simple and cheap. The key is prevention: ventilate the car immediately after rain to reduce moisture buildup. Regularly apply lubricant to the tracks to keep them flexible and rust-free. For deep rust, you can remove it yourself and repaint, or have a repair shop replace the seal. Though a minor issue, it's common—watch other parts to prevent rust and maintain overall protection. Develop a habit of checking and avoid professional tools to save hassle.
