How to Deal with Rust Spots on Your Car by Yourself?
2 Answers
You can use ultra-fine water sandpaper dipped in water to gently sand off the rust spots, then wipe them completely clean and apply a layer of primer to ensure the rust does not spread or worsen. Apply toothpaste in small circular motions over the scratches. After rain or washing the car, reapply to reduce the visibility of the scratches and also to isolate and prevent rust.
Don't rush to the repair shop when you find rust on your car - many small spots can be handled yourself. First, use sandpaper to thoroughly grind the rusted area until the bare metal shows. Remember to wear a mask while sanding, as inhaling those rust particles isn't good. After cleaning the surface, apply a thin coat of rust-preventive primer, then use matching topcoat paint for touch-up after it dries completely. Last time I dealt with small rust spots on my door edges, I specifically bought a mini spray can kit - easy to use and leaves no traces. After repair, it's best to apply a layer of car wax for protection, especially after highway driving in rain or snow when you should promptly rinse the undercarriage. During regular car washes, don't just focus on the body shell - carefully dry water accumulation points like wheel arches and door seams, otherwise you'll have to redo the work next year.
