I'm interested in seeing how this plays out. I have never gotten any kind of marker to stay on my plant labels (including old Sharpie permanent markers).

For context, I am in the PNW on the coast. It is always wet here. I have tried multiple types of permanent marker (Bic's Shapie knock off, Staples' Shapie knock off, and Sharpie are the ones I remember for sure) on both plastic plant labels and wood and the writing is always completely gone in less than a week.
