Yeah, I got into them a lot more recently, and my path was looking for more refillable/customizable brush pens (I.e., coming from Tombow, Faber-Castell Pitt, Kuretake's confusing lineup, etc.). Thinking about use with watercolors landed me unfortunately deep in Noodler's to start.
That makes sense. Noodler wasn't on my radar at all. I don't think they existed yet. I was used to "you simply can't put waterproof ink in any pen but a rapidograph" being an absolute fact of life. Except iron gall which you'd better rinse out at end of day. Other than that I used dip pens.
Rinse out iron gall at the end of the day, right. Yes. Of course. That's the only sensible thing to do. *nervously eyes the Preppy on my desk that I inked with R&K Scabiosa last September* The nib isn't slowly dissolving, it's just increasing the channel width for a wetter flow in a Preppy 02/EF!
I honestly have no idea. That was Montblanc's advice when dealing with their document blue at the time (which no longer contains iron gall). I still adhere to it, but I know a lot of gall inks have changed formula and are gentler, now.
I'd certainly not push my luck with a pen I had a sentimental attachment to. While I love my Preppies (and have too many of the Wa designs), I love the concept of them more than any individual pen. If I wreck one with neglect or poor choices, that's absolutely fine, now I've learned their limits.
Actually, I'm pretty sure that's not even a joke. It's certainly not worse for the wear, and comparing my initial ink log entry to how it writes today than I remember it working when I first inked it up last year, I think it's better. I did pull the nib out and rinse it off once. Preppy's rule.
