How to Deal with Rust Spots on a Sedan?
2 Answers
Rust should first be removed, and then some high-quality anti-rust and waterproof coatings can be chosen for repair. Here are some rust removal suggestions: 1. When performing rust prevention work on a car, it is important to note that the best paint to use is the same type as the car's original paint. 2. When directly polishing for chassis rust prevention care, the quality largely depends on the chassis care facility chosen by the owner. In general small auto repair shops, the rust prevention materials used for chassis protection are low-end, and the uniformity of the spray coating is also unreliable. Therefore, to achieve excellent results in this protection process, it is recommended to go to a 4S shop.
I noticed some rust spots on my car, just like the door edges on my old car last time. It's actually not hard to deal with. First, pick a sunny day to make sure the car body is dry, then wipe the rust spots clean with a dry cloth—keep them away from water. Next, gently sand the area with sandpaper until the bare metal shows, using soft motions to avoid damaging the primer. After that, spray some rust remover or rust-proof paint, let it dry completely, then apply primer and topcoat, making sure the color matches the factory finish. When washing your car, always dry areas where water collects, and avoid parking under trees or near the seaside—rainwater and salt accelerate corrosion. Regularly check rust-prone areas like wheel arches or the undercarriage; catching rust early and handling it simply can save you from major repairs later.
