How to Deal with Car Scratch Rust Prevention?

[HenryFitz]

Apply toothpaste in a gentle circular motion on the scratched area. Reapply after rain or car washing. This can reduce scratch marks and also act as a barrier against rust, providing short-term protection. Perform body glaze sealing to form a strong mesh-like protective film, enhancing the hardness of the paint surface. Coating can achieve a similar effect. For the scratched area, take it to a repair shop or 4S store for repainting.

If you find scratches on your car body, don’t procrastinate, especially when the metal is exposed. Last week, my car’s left door got scratched by a branch, so I quickly handled it myself: first, I used a clay bar to clean around the scratch, then gently sanded off the rust spots with 2000-grit sandpaper, and finally carefully applied touch-up paint with a paint pen. If you don’t have a touch-up pen, applying clear nail polish temporarily can also prevent rust. The key is to act quickly. Last time, my colleague ignored it, and three months later, rust bubbles formed around the scratch—costing over 500 yuan to fix at the repair shop. Usually, try not to park near bushes or walls, and applying a layer of wax after washing can protect the paint.
