How to Deal with Rust Spots on a Car?

[Corbin]

Use a grinder to sand the rusted area, thoroughly removing all traces of rust. Spray some expanding foam, then trim off the excess foam. Wipe the area clean and apply a layer of rust inhibitor. Once the adhesive is dry, use a grinder to smooth the edges, then apply body filler and sand it with sandpaper.

It's really annoying to see rust spots on the car! A while ago, a few small yellow spots appeared on the edge of my car's hood, so I slowly sanded off the rust with 800-grit sandpaper and cleaned it with alcohol. Then, I used a touch-up pen about the size of a nail polish bottle to dab on the paint—make sure to choose the right color. Remember to apply thin layers, with half-hour intervals between each layer, and finally polish it. Don’t always park under trees; tree sap and bird droppings corrode the paint really fast. When washing the car, pay extra attention to areas like the wheel arches where rust tends to hide. Rust spots on a car are like broken skin—if not treated promptly, they can spread and worsen, so take action immediately when you spot an issue.
