Need help on making text scrinkwrap neatly over very rough surface

I want to put text over a very uneven surface using the shrinkwrap modifier.

The uneven surface is a cargo container that has a wall surface somewhat like railroad ties.

I tried numerous approaches, but in each case the text would not wrap neatly onto the rough surface (as it normally does with smooth surfaces).

I even tried using the subsurface modifier on the wall mesh to give it more verticies but it still does not help.

If anyone has any tips or ideas, please let me know, thanks! :slight_smile:
