They are plastic today because earlier they were steel and rusted. Thus the “rustproof undercoating” which some dealers offered. A mechanic said my 1990 Honda CRX was mostly rust after 6 years in the Northeast US.

Rust is an entirely different process though. You can mitigate it with sacrificial anodes, for example (that's how steel ships survive bobbing around in salt water).
