Rust and corrosion can be found in cavities of the car body and other metal structures. In order to get rid of it and prevent it from happening again, we need to understand why it happened in the first place. Only with a clear diagnosis will we be able to take action and fix
If you want to clean and derust the box sections of a car, it is only possible if all the cavities are opened up. This means that the welds will also have to be repaired, which creates new problems because the new welds are unprotected.
Sealing an already-rusted box section using protection like paint or underseal will not stop the rust from continuing to damage the metal. In fact, it will just trap the rust and the damaging chemicals inside, making the problem worse in the long run. You need to remove the rust and the damaging chemicals from the car body before you do anything else.
