Not sure what the grey stuff actually is but you may have to get it bead (sand) blasted.
If the glass bead that is used is one of the finer grades a very satisfactory finish can be acheived with a good operator.
Make sure you diassemble and mask it up properly first though.
A proper wash down afterwards is also very important to remove the abrasive particles, it gets *everywhere*.
