[DML] Engine clean up

[saintern <saintern@xxxx>]

does anyone know of a good way of getting the back section of the underbody
that surrounds the engine back to its original color......I've tried to
clean it , and it looks nice, but when I come back the next day it looks
like it lost the deep black color to it.....I was thinking of using "BAck to
Black"....any ideas/suggestions?
