@Biggles50 Leo,
Where did I say those tracks were realistic?
I said it was testing.
Maybe consider asking or discussing before making assumptions about what others know or don’t know.
The not being realistic is even addressed in my actual blog post.
So no, I don’t need to rethink my track finishing because visual impact is more important to me than a strictly realistic appearance for the tracks. Yes, I’ve known about the manganese for decades.
Of course, modeler’s should finish models in a manner that suits their tastes and priorities.
