As I mentioned in this thread and this second thread, both in the General Pen Topics/Repari Q&A forum, I'm beginning to suspect that Renew-Point Esterbrook pens can't stop Noodler's Black ink from creeping past the feed and nib to the seam where the section and inner cap meet.
What I mean is, even with an Esterbrook-brand Renew-Point nib in my SJ, tightened reasonably into the section (the section is undamaged, as far as I can tell), and treating the pen very nicely on my short commute between work and home, Noodler's Black keeps ending up on the edge of the section and getting on my fingers.
Has anyone else here had that experience, or its pleasant opposite, or some other experience with Noodler's "bulletproof-ink-creep" and Renew-Point Esties?
Edit: Just now I cleaned the Noodler's out and put in Skrip Blue (Slovenian). I hope a few days will tell whether Skrip Blue stays inside the feed and nib, and off of the section.
