Will the rust on the car door expand?

Many cases of car door rust are caused by rainwater corrosion. After all, rain is unavoidable, and sometimes forgetting to clean it can lead to rust on the car door, affecting the car's appearance. Some damages that are not addressed in time can also rust over time, and the rusted area will grow larger, requiring timely treatment. Here are the methods to deal with car door rust: 1. If the rust appears on the surface and the area is small, you can use water sandpaper to grind off the rust and then spray a layer of anti-rust paint. 2. If the rust has damaged the primer, you need to remove the rust by grinding and then spray the primer, followed by topcoat spraying. 3. If the car door is severely rusted with large areas of paint peeling, you need to thoroughly scrape off the rusted paint, fill and level it with putty, and then spray paint after the putty hardens. 4. If the car door is rusted through, it is generally not recommended to repair it, as the repair effect is limited and rust may reappear after some time. It is more advisable to replace the door.
I used to have some small rust spots on the edge of my car door. At first, I didn't pay much attention, but after a few months, they grew significantly larger. This mainly happens because rust gradually corrodes the surrounding areas, especially during rainy days or when the air is humid. Now, I'm learning to handle it myself. First, I gently sand off the rust with sandpaper, then apply a layer of rust-proof paint, and finally spray some car paint to cover it up. If left untreated, rust on car doors can indeed spread. Over time, it might affect the door's operation or the appearance of the paint. Regular car washing and waxing can also prevent rust spots from spreading, and it's crucial not to let water accumulate in the door seams. All this comes down to regular maintenance. Don't be as careless as I was initially, letting small issues turn into big problems that end up costing more to fix later.
