Water resistance, how important to you?

[pw1224]

I generally have about 1 incident a year in which I manage to jostle a bottle or cup of drinking water and it gets on my papers. Fortunately, the only notes I lost were ones I really didn’t need that much any more but I vividly remember my frustration. I also tend to have sweaty hands so I prefer inks that are at the very least water resistant. I’m willing to risk the occasional ink stain. Sailor Seiboku is one of my all-time favorite inks. Noodler’s HOD and Kung Te Cheng are great but I won’t use them in all of my pens. I just got some Montblanc Permanent Black and really like that. On a lark, I scribbbled something on some scrap paper with the MB Permanent Black, let it sit for a day, then held the paper under a running tap for a while. I let the paper soak/air dry on my bathroom counter. No ink ran at all. Nothing disappeared. I’m impressed.
