Hello,
Tim, I would have loved to answer your question, before it became a hostile attack, as far as my experience overlapped your demanding qualifications. I guess now you, or others will have to just give it a go to see how it suits your work. But my meaning was actually that over time and in various outdoor conditions these lines are relatively durable, i.e. they don't wash away, they don't fade and they don't rub off.
Maybe that's one drawback or maybe it is an extra incentive to think clearly before putting ink to wood.
Greetings,
Don Wagstaff
