How to Deal with Car Body Rust?

After the car body rusts, anti-rust treatment should be applied before repainting. Rust often appears on the car body, mainly due to direct contact between the metal sheet and the external environment after scratches. Common causes include collisions, scrapes, and prolonged parking leading to rust. Methods to prevent car rust: 1. Avoid frequently covering the car with a car cover; 2. Apply toothpaste for protection; 3. Perform glaze sealing on soft paint surfaces. If the rust is not severe, you can first use very fine sandpaper dipped in water to gently remove the rust spots, clean it thoroughly, and apply a layer of primer to ensure the rust does not spread or worsen. For new scratches, clean them and apply primer directly. It's advisable to prepare a touch-up pen in advance. After the primer dries, use sandpaper to smooth it out, then use the touch-up pen for color matching.

I used to have an old car that also had rust issues, and handling it myself was quite simple. First, sand the rusty area clean to expose the metal surface, then apply a rust converter to turn it into a black anti-rust layer, and finally spray some matching car paint and clear coat for coverage. Always make sure to dry the car after washing, especially areas like the wheel arches where water tends to accumulate and cause corrosion. I’ve done this several times in my garage, saving a lot on repair costs and extending the car’s lifespan. The key is to spot small rust spots early before they spread to the internal structure. I recommend buying a rust removal tool kit online—it only costs a few dozen bucks. Remember to wear gloves and a mask when working; safety first.

From the perspective of a repair shop, body rust is categorized into minor and severe cases. For surface rust, start by removing it with a grinding wheel or wire brush, then seal it with epoxy primer to prevent recurrence. In cases of severe rust that has penetrated through, welding new metal sheets or replacing parts may be necessary. It's advisable to seek professional services, as improper handling can leave safety hazards. Rust on the chassis requires extra caution as it relates to driving safety. Regular maintenance should include checking body seams and joints, addressing any signs of rust promptly. Our shop is equipped with specialized tools to assess rust depth and determine if it affects structural integrity. Customers report feeling more at ease driving after our treatments.

With over 20 years of driving experience, I deeply understand that body rust should never be ignored. Take action in the early stages, such as using a brush and chemical rust remover to clean off rust spots, then apply protective paint. Leaving it untreated for too long will thin the metal due to corrosion, making it very dangerous in case of a collision. Remember to wax your car regularly after washing to prevent moisture, especially in coastal areas or on roads treated with salt in winter, where rust is more likely. From personal experience, repairing large rust holes is costly and troublesome. It's best to make it a habit to inspect the car body once a year, especially hidden areas like door frames and the undercarriage. Timely repairs can extend your car's lifespan and give you peace of mind while driving.
