For a base colour on the areas to be exposed I used MR.Metalcolor Iron , which was then polished. A coat of Future, then primer (Tamiya Flat Red plus some Dark Grey) to finish. Washed the higher areas with meths and the picked away the primer with flat cut toothpick to expose the metal beneath. Finished with future to give an oily 'sheen'. Floor still has to washed with dirt/oil etc but this will wait till all other floor details are in.
