How to Deal with Rust on the Wheel Arches and Multiple Body Parts of the Baojun 730?
2 Answers
The methods to deal with rust on the wheel arches and multiple body parts of the Baojun 730 are as follows: 1. Use a touch-up pen for minor scratches: If the rust is not severe, start by using very fine sandpaper dipped in water to gently remove the rust spots, sanding in straight lines in the same direction. After completely cleaning the area, apply a layer of primer. Once dry, sand it smooth with water sandpaper, then apply the original factory paint over the primer. If the original factory paint is unavailable, a touch-up pen can be used instead. 2. Use toothpaste to remove rust spots: For minor scratches, gently apply ordinary toothpaste in a circular motion over the scratches. Reapply after rain or washing the car. This can help reduce the appearance of scratches, especially on white car paint, where the effect is most noticeable.
I've driven many cars and found that the rusting issues on the Baojun 730's wheel arches and body are quite common, often due to aging of the metal coating, prolonged exposure to rain or salt spray, or failed sealing strips allowing water ingress. Assessing the extent of rust is crucial; for minor cases, sanding off the rust and applying automotive primer and topcoat can restore protection. The wheel arch area, where plastic meets metal, tends to trap mud and water, requiring thorough cleaning. Severe rust may require professional repainting or part replacement, costing anywhere from a few hundred to over a thousand yuan. Regular maintenance is key—focus on cleaning the wheel arch crevices during washes and apply anti-rust wax to the body biannually. If rust significantly compromises structural safety, address it promptly to avoid further complications, as driving safety should always come first.
