Following the recommendation of someone who knows, I ordered three more pens. All fine nib Parker Vectors, one each black, dark blue, and red. They’re coming from India, so it will be several weeks before they arrive. I’m still waiting on the two Hero pens that I ordered a week or two ago, too. That shipment originated in China.
The Noodler’s Bulletproof Black ink has arrived, and entered service tonight in one of my Pilot pens. Now when I get overspray from the rinse hose, the log book and hourly log sheet should remain legible. A report will be forthcoming, but based on the drops of water and isopropyl alcohol that I intentionally splashed onto different parts of the page as an initial test, it looks promising.
