Rust Encruster

A rust encruster is a device used by Shredder in the 1987–1996 animated series in the Rust Never Slleeps episode. Originally, Krang planned to use an oxidizer rocket to blast the Technodrome from the Volacnic Asteroid to Earth, but that idea fails. Instead, Shredder uses the rust encruster to rust all metals on Earth. During confusion, Shredder and Krang plan to send the Technodrome to Earth..
