Amelinum, the unpaintable
Amelinum is a metal with properties that make it completely immune to any sort of paint. Nothing is able to stick to it. Theoretically it should be the most slippery substance in the Nevenian Realm, but it is not. It can be coated for a short moment, after the substance tries to stick to the metal, it starts creating micro vibrations which slowly repels any substance that comes into contact.
