How much rust on a car is OK?

If less than 25% of the thickness of the frame has been compromised we can pass it through as acceptable. It does matter where on the frame the degradation has occurred as well due to load-bearing concerns, but that's a good starting rule of thumb.

How bad is a little rust on a car?

While many drivers think of rust as nothing more than cosmetic issue, it can actually become a significant safety problem if it's not properly taken care of. Once rust penetrates the surface of your car and begins to attack your vehicle's frame, it will start to cause serious damage.

If left unchecked, rust will continue to grow worse and worse, until it has eventually eaten right through the material. This can leave things like tools and automobiles in a dangerously weakened state.

Which cars rust the most?

Does rain make car rust worse?

Rain. Rust happens when a material that contains iron is exposed to moisture. When the two substances come into contact with each other, it causes an atomic reaction that results in oxidation. The most obvious way for moisture to come into contact with the metal in your car is rain.
