    Scale Rust: Scale rust is the next stage of rusting. This happens when the surface rust isn’t treated and it starts to decompose and seep further into the metal. You may start to see bubbles forming in your car’s paint. When rust penetrates like that, they cause a rough type of damage called scale.

    Penetrating Rust: After prolonged exposure and no treatment, the steel is converted to brittle iron oxide. This means the rust has eaten into your car’s metal. This penetrating rust may lead to weakened frames and suspended holes. You shouldn’t wait until this happens before you start to treat rust. This is very damaging.
