Chery Tiggo 3 door rust can be addressed by the following methods: 1. If the rust appears on the surface and the area is small, you can use water sandpaper to grind off the rust and then spray a layer of anti-rust paint; 2. If the rust has damaged the primer, the rust needs to be ground off, followed by primer spraying, and then topcoat spraying; 3. If the door rust is more severe, with large areas of paint peeling, the rusted paint on the door needs to be completely scraped off, filled and leveled, and then sprayed after hardening. The Chery Tiggo 3's headlight assembly is equipped with lenses, and LED daytime running lights are installed in the fog light area. In terms of configuration, the car features a three-spoke multifunction steering wheel adjustable up and down, electrically adjustable exterior rearview mirrors, a rear wiper, an onboard computer display, parking sensors, and a rearview camera.
I personally dealt with the door rust issue on a Chery Tiggo 3, and first off, it's quite common, especially if the car is frequently exposed to rain or salty environments. For a DIY solution, it's pretty straightforward: Check the lower part and edges of the door for rust, then gently remove the surface rust with a small brush or sandpaper, being careful not to damage the metal excessively. After cleaning, wipe the area thoroughly with alcohol and let it dry completely. Then, apply a rust-preventive primer, wait for it to dry, and finish with an automotive-grade topcoat matching the original color. The whole process takes about one to two hours—just remember to wear gloves and a mask for protection. Tools like sandpaper and paint can be easily found at auto parts stores. Finally, regular waxing after painting helps reduce moisture damage. For prevention, try parking in dry areas and rinse door seams thoroughly during car washes to avoid recurrence. If the rust is severe and internal framing might be compromised, it's best to consult a professional to assess whether panel beating or part replacement is needed, as delays could affect door operation and safety.
Regarding the solution for Chery Tiggo 3 door rust issues, my experience suggests prioritizing professional repair. Rust typically starts from minor scratches, exposing the metal and making it prone to internal structural corrosion. The correct procedure is to first visit a 4S shop or authorized repair center to assess the extent of rust damage. They may use professional rust removers to clean off the rust layer, followed by touch-up painting and sealing. In severe cases, replacing rusted door panels or reinforcing the frame may be necessary, with costs ranging from a few hundred to over a thousand yuan—far more worthwhile than safety risks. Daily precautions include avoiding parking in rainy conditions or coastal areas, and promptly drying door seams after car washes. Regularly inspect for rust spots; minor issues can be addressed with rust-proof sprays if manageable. Remember, rust is no trivial matter—it can affect door locks and overall structural integrity. Early resolution ensures peace of mind.
