Franklin,
        A gray eraser is quite a bit more abrasive than your standard
'pinkie', in an rotary electric eraser it can do a fair amount of work
quickly. As far as a Dremel, they make bronze and steel wire wheels that
can also do the job well. As previously mentioned, an stainless steel
aperture mask can really help and a light touch is a must....
