Which process protects a steel body shell against corrosion?

  • A.Wax injection alone
  • B.Galvanising after assembly, which coats the completed shell including all of the internal cavities within it
  • C.Zinc coating followed by cathodic electrocoat priming
  • D.A single coat of paint applied directly to the bare steel, which seals the surface against any moisture ingress

Answer: C

Modern shells use galvanised steel, are dipped and electrocoated so that the primer reaches every cavity, and are then sealed and wax injected. The multilayer system is why bodies now last far longer than those of the nineteen seventies. Galvanising a completed shell is impractical because of the temperature involved and the difficulty of draining.
