    I've some Caterpillar cad that's close to a half-century old, and its still immaculate.

    I "plated" a brass oil fitting with mercury once.

    It evaporated. But coulda passed judging.

    OK, Thanks for all of your replies folk,
    There was a black finish to all the non exposed parts of the head bolts and washers, so I heated the bolt heads and the washers until they were blue and quenched them in oil, to leave an almost parkerized look.
    Thanks again, Ivor.
