Is there a sense of the scale of the finish roughness with this product?

That brings up an interesting point. The biggest challenge, to my
mind, in modeling steel castings in HO scale isn't roughness; it's
smoothness. A couple coats of paint mopped on over the years long ago
covered any surface roughness. The distinctive thing about castings is
their smooth, rounded forms; all outside corners are slightly rounded,
and all inside corners have fillets. Often times the fillets have
multiple little gussets worked into them.

Note the details in the image in the link.

The plate and bar stock items all have square edges and sharp corners.
The castings, such as the poling pockets, have radii everywhere. The
structural steel is somewhere in between, as it has fillets in the
inside corners. As to surface finish, it all looks the same.
