If you purchase a quality Ink it is practically bomb proof it is one of the best things the Victorians managed to get right, the pigment is "Lamp Black" which is inherently inert and the binders I find are oil and water proof when dry. It has many uses and is an indispensable addition to the gun restorers Armoury with the Artists oil colours Alkanet and Linseed oil.
The art of restoring a stock as to making a new one has always been a far harder proposition in my opinion in geting it to look right!
