Hey guys, I recently got as a gift a Parker Urban Premium Metallic Pink fountain pen. I really enjoy the greyish trimming that Parker chose for this version of the pen, even though I find quite disturbing the fact that the nib is plain steel and not plated. [same goes for the Premium matte black version that I had been eyeing for quite some time] Anyway, I happened to lay the Urban next to a Lamy Studio Imperial Blue and then I thought about how the Studio would look in the same greyish trim. I searched online and found about a process called "bluing" that is supposed to oxidize steel and turn it into a grey/bluish grey or even black color. Is anyone familiar with such a process? I am afraid I lack the dexterity for such a fine modification in my pen, so I would like to have some (detailed ) explanation of what I have to do, what I should be extra careful about, or [even better] where I can find someone to perform this modification for me. Also, can I do the same thing to the nibs too? Or to gold plated steel? I was considering a Cross Century 2 fountain pen in black but unfortunately it only comes with GT. I would be thrilled if I could turn it into an all black stealthy pen. Thanks in advance
